Yoga is an evolutionary process in the development of human consciousness. Evolution of total consciousness does not necessarily begin in any particular man rather it begins only if one chooses it to begin. The vices like use of alcohol and drugs, working exhaustively, indulging too much in sex and other stimulation is to seek oblivion, a return to unconsciousness. Indian yogis begin from the point where western psychology end. If Fraud’s psychology is the psychology of disease and Maslow’s psychology is the psychology of the healthy man then Indian psychology is the psychology of enlightenment. In Yoga, it is not a question of psychology of man rather it is a question of higher consciousness. It is not also the question of mental health, rather, it is question of spiritual growth.
