Muladhara (Sanskrit: मूलाधार, Mūlādhāra), meaning "root place" is the first of the main seven chakras according to Hinduism. It may be represented as red, although its root square form is usually colored yellow. That 'lotus' of muladhara chakra has four petals, metaphorically referring to the four vritties that find expression in this chakra: dharma (psycho-spiritual longing), artha (psychic longing), kama (physical longing) and moksha (longing for spiritual liberation).
Muladhara chakra is the metaphysical seat of Lord Ganesha within the subtle bodies of man.
According to Hinduism within this chakra resides/sleeps the kundalini shakti, the great spiritual potential, waiting to be aroused and brought back up to the source from which it originated, Brahman. It is also believed that Muladhar is a subtle abode of the Hindu God, Ganapati. And in the highest revered prayer for Ganapati, the Ganapati Atharvashirsha, it is mentioned that 'one who worships Lord Ganapati would easily grasp the concept and realize Brahman.
Muladhara is the base from which the three main psychic channels or nadis emerge: the Ida, Pingala and Sushumna .
