The terms afterlife, life after death, and hereafter refer to the supposed continuation of the soul, spirit or mind of a being after physical death. The major views on the afterlife derive from religion, esotericism and metaphysics. In many popular views, this continued existence often takes place in a spiritual or immaterial realm. Deceased persons are usually believed to go to a specific realm or plane of existence after death, usually determined by their actions during life. By contrast, the term reincarnation refers to an afterlife that is a continuation of physical life in this world. Those who are skeptical of the existence of the afterlife may believe that it is absolutely impossible, such as the materialist-reductionists, who state that the topic is supernatural, and therefore either does not exist or is unknowable.
In metaphysical models, theists generally believe some sort of afterlife awaits people when they die. Atheists generally do not believe that there is an afterlife. Members of some generally non-theistic religions such as Buddhism, tend to believe in an afterlife (such as reincarnation) but without reference to God.
Agnostics generally hold the position that, like the existence of God, the existence of other supernatural phenomena such as the existence of souls or life after death is unverifiable and therefore remains unknown. Some philosophies (i.e. humanism, posthumanism, and, to some extent, empiricism) generally hold that there is not an afterlife.
Many religions, whether they believe in the soul’s existence in another world like Christianity, Islam and many pagan belief systems, or in reincarnation like many forms of Hinduism and Buddhism, believe that one’s status in the afterlife is a reward or punishment for their conduct during life.
The Society for Psychical Research was founded in 1884 with the express intention of investigating phenomena relating to Spiritualism and the afterlife. Its members continue to conduct scientific research on the paranormal to this day. Some of the earliest attempts to apply scientific methods to the study of phenomena relating to an afterlife were conducted by this organization. Its earliest members included noted scientists like William Crookes, and philosophers such as Henry Sidgwick and William James.
J. B. Rhine, who was critical in the early foundations of parapsychology as a laboratory science, was committed to finding scientific evidence for the spiritual existence of humans. Scientists who have worked in this area include Raymond Moody, Susan Blackmore, Charles Tart, William James, J. B. Rhine, Ian Stevenson, Michael Persinger and Pim van Lommel among many others.
Some, such as Francis Crick in 1994, have attempted a ‘scientific search for the soul’. Frank Tipler has argued that physics can explain immortality, though such arguments are not falsifiable and thus do not qualify as science.
Charles Tart conducted research into out-of-body experiences, or OBEs, that indicated the possibility that a person might be able to perceive targets at a distance removed from the physical body. Later investigations have failed to find evidence that “out-of-body” experiences transcend the confines of the brain. For example, one hospital placed an LED marquee above its patients’ beds which displayed a hidden message that could only be read if one were looking down from above. As of 2001, no one who claimed near-death experience or out-of-body experience within that hospital had reported having seen the hidden message.
In 2008 however, Penny Sartori, an intensive care nurse from Swansea, published an academic book about near death experiences following 10 years of research. Sartori found that people who went through out-of-body experiences felt as if they floated above themselves and were able to accurately recount what had happened in the room even though their bodily eyes were closed. The scientific credibility and neutrality of the research are disputed.
Currently, a large study is set to examine near-death experiences in cardiac arrest patients. Doctors at 25 UK and US hospitals will study 1,500 survivors to see if people with no heartbeat or brain activity can have "out of body" experiences.
Arriving at one's reward in afterlife was a demanding ordeal, requiring a sin-free heart and the ability to recite the spells, passwords, and formulae of the Book of the Dead. In the Hall of Two Truths, the deceased's heart was weighed against the Shu feather of truth and justice taken from the headdress of the goddess Ma'at. If the heart was lighter than the feather, they could pass on, but if it were heavier they would be devoured by the demon Ammit. Egyptians also believed that being mummified was the only way to have an afterlife. Only if the corpse had been properly embalmed and entombed in a mastaba, could the dead live again in the Fields of Yalu and accompany the Sun on its daily ride. Due to the dangers the afterlife posed, the Book of the Dead was placed in the tomb with the body.
The Pahlavi text Dadestan-i Denig ("Religious Decisions") from about 900 CE, describes the particular judgment of the soul three days after death, with each soul sent to heaven, hell, or a neutral place (hamistagan) to await Judgment Day.
In his Myth of Er, Plato describes souls being judged immediately after death and sent either to the heavens for a reward or underground for punishment. After their respective judgments have been enjoyed or suffered, the souls are reincarnated.
The Greek god Hades is known in Greek mythology as the king of the underworld, a bleak place in between the place of torment and the place of rest, where most souls live after death. Some heroes of Greek legend are allowed to visit the underworld. The Romans had a similar belief system about the afterlife, with Hades becoming known as Pluto. The Trojan prince Aeneas, who founds the nation that would later become Rome, visits the underworld according to the epic poem Aeneid.
The Talmud offers a number of thoughts relating to the afterlife. After death, the soul is brought for judgment. Those who have lead pristine lives enter immediately into the "World to Come." Most do not enter the World to Come immediately, but now experience a period of review of their earthly actions and they are made aware of what they have done wrong. Some view this period as being a "re-schooling", with the soul gaining wisdom as one's errors are reviewed. Others view this period to include punishment for past wrongs. At the end of this period, approximately one year, the soul then takes its place in the World to Come. Although punishments are made part of certain Jewish conceptions of the afterlife, the concept of "eternal damnation," so prevalent in other religions, is not a central tenet of the Jewish afterlife. According to the Talmud, eternal punishment is reserved for a much smaller group of malicious and evil leaders, either whose deeds go way beyond norms, or who lead large groups of people to evil. In the Talmud, completed by 500 AD, non-Jews who are purely evil cease to exist in any realm when they die.
The Book of Enoch describes sheol as divided into four compartments for four types of the dead: the faithful saints who await resurrection in Paradise, the merely virtuous who await their reward, the wicked who await punishment, and the wicked who have already been punished and will not be resurrected on Judgment Day. It should be noted that the Book of Enoch is considered apocryphal by most denominations of Christianity and all denominations of Judaism.
The book of 2 Maccabees gives a clear account of the dead awaiting a future resurrection and judgment, plus prayers and offerings for the dead to remove the burden of sin.
Maimonides describes the Olam Haba ("World to Come") in spiritual terms, relegating the prophesied physical resurrection to the status of a future miracle, unrelated to the afterlife or the Messianic era. According to Maimonides, an afterlife continues for the soul of every human being, a soul now separated from the body in which it was "housed" during its earthly existence.
Jesus also maintained that the time had come when the dead would hear the voice of the Son of God, and all who were in the tombs would come out, those who had done good to the resurrection of life, and those who had done evil to the resurrection of judgment. According to the Gospel of Matthew, at the death of Jesus tombs were opened, and at his resurrection many saints who had died emerged from their tombs and went into "the holy city," presumably Jerusalem. No other New Testament account includes this event.
The Last Day: Jesus compared the kingdom of heaven, over which He rules, to a net which was thrown into the sea and gathered fish of every kind. When it was full, men drew it ashore and sat down and sorted the good into vessels but threw away the bad. So it will be at the close of the age also known as the Last Day. The angels will separate the evil from the righteous and throw them into the furnace of fire. Then the righteous will shine like the sun in the kingdom of their Father.
Jesus and the New Testament writers of the Bible books mention notions of an afterlife and resurrection that involve ideas like heaven and hell. The author of Luke recounts the story of Lazarus and the rich man, which shows people in Hades awaiting the resurrection either in comfort or torment. The author of the Book of Revelation writes about God and the angels versus Satan and demons in an epic battle at the end of times when all souls are judged. There is mention of ghostly bodies of past prophets, and the transfiguration.
Hippolytus of Rome pictures Hades as a place where the righteous dead, awaiting in the bosom of Abraham their resurrection, rejoice at their future prospect, while the unrighteous are tormented at the sight of the "lake of unquenchable fire" into which they are destined to be cast.
On the other hand, the enlightenment produced more rationalist philosophies such as deism. Many deist freethinkers held that belief in an afterlife with reward and punishment was a necessity of reason and good moral order.
Christian theologians Thomas Aquinas and Jonathan Edwards wrote that the saved in heaven will delight in the suffering of the damned. Hell, however, doesn't fit modern, humanitarian concepts of punishment because it can't deter the unbeliever nor rehabilitate the damned, this however, does not affect the Christian belief which places Biblical teaching above the ideas of society. Some Christian believers have come to downplay the punishment of hell. Universalists teach that salvation is for all. Jehovah's Witnesses and Seventh-day Adventists, though they have among the strictest rules on how to conduct their lives, teach that sinners are destroyed rather than tortured forever.
For the living are conscious that they will die; but as for the dead, they are conscious of nothing at all, neither do they any more have wages, because the remembrance of them has been forgotten.
They believe that following Armageddon a resurrection in the flesh to an Edenic Earth will be rewarded to both righteous and unrighteous (but not wicked) dead. Acts 24:15 states, "“I have hope toward God . . . that there is going to be a resurrection of both the righteous and the unrighteous.”
Eternal death (non-existence) is the punishment for sin lacking repentance after Armageddon. Although those who are not dead when Armageddon occurs will be judged and possibly slain during Armageddon because of their potential regretless sins. They believe that death is the price for sinning (that is why most dead will be resurrected - they paid the price already).
Islam teaches that the purpose of man's creation is to be kind to other human beings and to worship the Creator of the Heavens and Earth , Allah, the Arabic word used to refer to The One and Only God of the Abrahamic Tradition. Islam teaches that life lived on this Earth is a test for man to determine each individual's ultimate reward or punishment in the afterlife, which is eternal and everlasting.
Some practitioners of eastern religions follow a different concept called metempsychosis which purposes that human beings can transmigrate into animals, vegetables, or even minerals. One consequence of the Hindu and Spiritist beliefs is that our current lives are also an afterlife. According to those beliefs events in our current life are consequences of actions taken in previous lives, or Karma.
Hindus also believe in 'Karma'. 'Karma' is the accumulated sums of one's good or bad deeds. According to Hinduism the basic concept of Karma is 'As you sow, you shall reap'. So, if you have a lived a good life you will be rewarded in the afterlife. Similarly your sum of bad deeds will be mirrored in your next life.
In Tibetan Buddhism the Tibetan Book of the Dead explains the intermediate state of humans between death and reincarnation. The deceased will find the bright light of wisdom, which shows a straightforward path to move upward and leave the cycle of reincarnation. There are various reasons why the deceased do not follow that light. Some had no briefing about the intermediate state in the former life. Others only used to follow their basic instincts like animals. And some have fear, which results from foul deeds in the former life or from insistent haughtiness. In the intermediate state the awareness is very flexible, so it is important to be virtuous, adopt a positive attitude, and avoid negative ideas. Ideas which are rising from subconsciousness can cause extreme tempers and cowing visions. In this situation they have to understand, that these manifestations are just reflections of the inner thoughts. No one can really hurt them, because they have no more material body. The deceased get help from different Buddhas who show them the path to the bright light. The ones who do not follow the path after all will get hints for a better reincarnation. They have to release the things and beings on which or whom they still hang from the life before. It is recommended to choose a family where the parents trust in the Dharma and to reincarnate with the will to care for the welfare of all beings.
Some Neopagans believe in personal reincarnation, whereas some believe that the energy of one's soul reintegrates with a continuum of such energy which is recycled into other living things as they are born.
Many Wiccans, though not all, profess a belief in an afterlife called the Summerland, a peaceful and sunny place where the souls of the newly dead are sent. Here, souls rest, recuperate from life, and reflect on the experiences they had during their lives. After a period of rest, the souls are reincarnated, and the memory of their previous lives is erased. Shi'a Muslims believe to Raj'a that can be understood as a limited reincarnation.
Adherents of The Grail Message , by Abd-ru-shin, also believe in reincarnation. They understand the human spirit to have many earth-lives, and many experiences in the so-called "beyond" on its path to maturity.
