“One may not give up work and prescribed duties all of a sudden; but by gradually developing Krishna consciousness, one can be situated in a transcendental position without being influenced by the material senses and the mind — by steady intelligence directed toward one’s pure identity. This is the sum total of this chapter. In the immature stage of material existence, philosophical speculations and artificial attempts to control the senses by the so-called practice of yogic postures can never help a man toward spiritual life. He must be trained in Krishna consciousness by higher intelligence.”
