“If, through yoga, the mind can be trained, then the mind is our friend. But if the mind is left untrained, then there is no possibility of leading a successful life. For one who has no idea of spiritual life, the mind is the enemy.” – Srila Prabhupada. Lord Krishna vehemently avers, “For him who has conquered the mind, the mind is the best of friends; but for one who has failed to do so, his mind will remain the greatest enemy” (Bhagavad Gita 6.6).
