The truly wise, the Jnani, who has realised the Reality, is the person who has given up the rights and obligations of caste and society, of age and status and lives in the constant awareness that all this is Brahman. He has understood that there is no manifoldness or diversity here; it is all One. (Sarvam khalu idam Brahman; Na iha nana asti kinchana). He knows that the entire Cosmos is constituted of the same Brahman, that there can be no second entity apart from Brahman.
The Trinity (Brahma, Vishnu and Rudra) are but the reflections of the one Brahman in each of the three strands or attributes -Sattva, Rajas and Tamas. The Rajas attribute is personified as Brahma, the Sattva aspect as Vishnu and the Tamas aspect is known as Rudra or Shiva or Ishvara. The entire Cosmos, including the World is the manifestation of the One Brahman through one or other, or some combination or other of these three attributes. So, the wise man will go beyond and beneath these three strands and seek the origin in the One. He alone deserves the name, Monk or Vairagi for he has noraga, or likes and dislikes.
