The king then said to Uddālaka Āruṇi - ‘O Gautama, whom do you worship as the Self?’ Uddālaka replied - ‘I worship the earth, revered king.’ The king said - ‘That which you worship as the Vaiśvānara Ātman is named Pratiṣṭhā (the support). This is why you have so many children and animals to support you’.
‘You enjoy eating food and you see your dear ones and everything pleasant. He who worships the Vaiśvānara Self thus enjoys eating food and is able to see his dear ones. He also has children in his family who shine with the radiance of Brahman (i.e., they become well known for their good conduct and scholarship). But the earth is like the feet of the Self.’ Then the king said - ‘If you had not come to me your feet would have become extremely weak’.
