SB 5.11.15 — My dear King Rahūgaṇa, as long as the conditioned soul accepts the material body and is not freed from the contamination of material enjoyment, and as long as he does not conquer his six enemies and come to the platform of self-realization by awakening his spiritual knowledge, he has to wander among different places and different species of life in this material world.
SB 5.11.16 — The soul’s designation, the mind, is the cause of all tribulations in the material world. As long as this fact is unknown to the conditioned living entity, he has to accept the miserable condition of the material body and wander within this universe in different positions. Because the mind is affected by disease, lamentation, illusion, attachment, greed and enmity, it creates bondage and a false sense of intimacy within this material world.
SB 5.11.17 — This uncontrolled mind is the greatest enemy of the living entity. If one neglects it or gives it a chance, it will grow more and more powerful and will become victorious. Although it is not factual, it is very strong. It covers the constitutional position of the soul. O King, please try to conquer this mind by the weapon of service to the lotus feet of the spiritual master and of the Supreme Personality of Godhead. Do this with great care.
