For those ascetics who are free from desire and anger, who have controlled their minds, and who know the Self — brahma-nirvana exists all around them. It is not somewhere far away. It is here, on every side.
The word 'abhitah' — all around — is striking. Just as light surrounds a lamp on every side without the lamp needing to search for it, so too for such realized souls, the peace of Brahman is everywhere. It does not need to be found. It is already there.
