SB 11.7.41
parthivesv iha dehesu
pravistas tad-gunasrayah
gunair na yujyate yogi
gandhair vayur ivatma-drk
Translation:
Although a self-realized soul may live in various material bodies while in this world, experiencing their various qualities and functions, he is never entangled, just as the wind which carries various aromas does not actually mix with them.
Purport:
Although we experience the wind as fragrant or foul, depending on the aromas it carries, the wind does not in fact change its actual nature. Similarly, although we regard a particular person as strong or weak, intelligent or retarded, beautiful or homely, good or bad, the pure spirit soul, who is the actual person, does not really possess any of the qualities of the body but is merely covered by them, just as the wind is covered by different aromas. Thus, a Krsna conscious person is always aware that he is different from the temporary body. He experiences the various transformations of the body, such as childhood, adolescence, adulthood and old age; but although he experiences the pains, pleasures, qualities and functions of that body, a Krsna conscious person never thinks that he is the body. He always understands that he is an eternal spirit soul, part and parcel of Lord Krsna. As stated in this verse, na yujyate yogi: he is not entangled. The conclusion is that one should never consider a Krsna conscious person in terms of bodily designation, but should see him as an eternal servitor of the Lord.
