SB 5.12.2
jvaramayartasya yathagadam sat
nidagha-dagdhasya yatha himambhah
kudeha-manahi-vidasta-drsteh
brahman vacas te ’mrtam ausadham me
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O best of the brahmanas, my body is filled with dirty things, and my vision has been bitten by the serpent of pride. Due to my material conceptions, I am diseased. Your nectarean instructions are the proper medicine for one suffering from such a fever, and they are cooling waters for one scorched by the heat.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The conditioned soul has a body full of dirty things — bones, blood, urine, stool and so forth. Nonetheless, the most intelligent men in this material world think they are these combinations of blood, bone, urine and stool. If this is so, why can’t other intelligent men be made with these ingredients, which are so readily available? The entire world is going on under the bodily conception and creating a hellish condition unfit for any gentleman’s living. The instructions given to King Rahugana by Jada Bharata are very valuable. They are like the medicine that can save one from a snakebite. The Vedic instructions are like nectar and cool water for one suffering from scorching heat.
