Having abandoned egotism, strength, arrogance, desire, enmity, property, free from the notion of “mine,” and peaceful, he is fit for becoming Brahman.
Read the commentary

Egotism : identifying the Self with the body, etc. Strength : that strength which is combined with passion and desire, but not the physical or any other strength : the latter being natural, its abandonment is not possible. Arrogance : which follows the state of exultation and leads to the transgression of dharma, as said in the smriti :

“When a man exults, he becomes arrogant, and when he becomes arrogant, he transgresses dharma”—

(Āpastamba-Dharmasūtra, 1-13-4).

Property : though a man is free from all passions of the mind and the senses, he may own so much of external belongings as is necessary for bodily sustenance and for the observance of his duties (dharma); but even this the aspirant abandons; i.e., he becomes a Paramahamsa-Parivrajaka, a samnyasin of the fourth or highest order. He does not regard even the bodily life as his. Peaceful : free from exultation and care. Such a devotee of wisdom is fit to become Brahman.
