Attraction and repulsion are rooted in all sense-objects. Man should never allow himself to be swayed by them, because they are the two principal enemies standing in the way of his redemption. Knowledge stands covered by the eternal enemy of the wise, known as desire, which is insatiable like fire. The senses, the mind and the intellect are declared to be its seat; screening the light of truth through these; it (desire) deludes the embodied soul. The senses are said to be greater than the body; but greater than the senses is the mind. Greater than the mind is the intellect; and what is greater than the intellect is the Self (soul). One should subdue the mind by reason and kill this enemy in the form of desire that is hard to overcome.
