The Knower is neither happy nor miserable, is not dispassionate nor attached to anything. He is neither a seeker, nor liberated. He is not this nor another.
See the impersonal and impartial nature of the Knower! The world consists of manifold dvandvas. Every time every one is after one or the other of these sets. The whole life is thus spent chasing some preference or prejudice, some likes or dislikes, some desire or hatred. Dispassion is another flair for seekers. In fact, any of these, when chased, makes one constricted and divisive. It makes the mind far from the wholesome purity it should gain.
As Krishna stresses in Gita, the spiritual seeker needs to develop a vision, by dint of which all sense of partiality, division and constriction will vacate the mind, and it will become worthy of the supreme knowledge and the bliss associated with it.
Yoga-yukta is lifting the mind from the stranglehold of all dvandvas, making it live and float in grandeur of transcendence, wherein neither of the dvandvas has any appeal for him. It is the highest level of purity and sublimity, where one sees only the supreme Truth and its wondrous display anywhere.
Krishna’s words in Gita are quite specific: Devoid of dvandvas, abiding constantly in sattva-guṇa, free of all kinds of concern, dwelling in the Self always (Gita 2.45 ).
The Seer is no seeker nor one liberated. He is not this or another. What an exalted state of enlightenment! As the Self is singular, the Self-realized one also is. See the wonder knowledge works!
