Sri Krishna in Bhagwat Gita says 'CHATUR VARNA MAYA SRISTIM GUNA KARMA VIBHAG SHAH' He says that on the inquiry of self realization, people undergo different step by step stages of awareness, and with it comes purity in their character. There are four steps or divisions of 'varna' according to ones' state of identifying with the self. SHUDRA (KAM)- VAISHYA (ARTH)- Kshatriya(DHARMA) and BRAHMAN (MOXA)
VAISHYA are those whose mind is engaged by the VISHAYA. VISHAYA means, subject or specialization or professional knowledge. Physics, Chemistry, Technology, Law, Economics, Politics, Management are example of the Vishaya. Another term for VISHAYA is ARTH or meaning, or knowledge behind every object, ego or positions of power. Vishaya contains VISH or poison because mind under influence of a subjects get anxiety, and insatiable demand of changes and controls. It is said that consumers of VISHAYA are intoxicating; and specialists for example, try always to wield more power and control in their hand.
