Lord Krishna brings out quite clearly and unmistakably the intimate connection between ethics and spirituality, between a life of virtue and God realization and liberation. Listing two sets of opposite qualities, the Lord classifies them as divine and demonical, and urges us to eradicate the latter and develop divine qualities.
Divine qualities are conducive to liberation and undivine qualities lead to bondage. Purity, good conduct and truth are indispensable to spiritual progress and for leading an honourable life. Therefore, a wise person, desiring success, must eradicate vice and cultivate virtue.
