SB 5.11.15
na yavad etam tanu-bhrn narendra
vidhuya mayam vayunodayena
vimukta-sango jita-sat-sapatno
vedatma-tattvam bhramatiha tavat
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
My dear King Rahugana, 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.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
When one’s mind is absorbed in the material conception, he thinks that he belongs to a particular nation, family, country or creed. These are all called upadhis, designations, and one has to become freed from them (sarvopadhi-vinirmuktam). As long as one is not freed, he has to continue conditioned life in material existence. The human form of life is meant for cleansing away these misconceptions. If this is not done, one has to repeat the cycle of birth and death and thus suffer all material conditions.
