The sages are those who know the real nature of the self in all beings. They see the selves to be of the same nature, though they are perceived in extremely dissimilar embodiments such as those of one endowed with learning and humility, a mere Brahmana, a cow, an elephant, a dog, a dog-eater etc., because they all have the same form of knowledge in their nature as the Atman. The dissimilarity of the forms observed is due to Prakrti (body) and not to any dissimilarity in the self; consequently they, the wise, perceive the self as the same everywhere, because all selves, though distinct, have the same form of knowledge.
