Brahman is outside every being and inside every being. It is in the moving creatures — animals, birds, humans — and in the unmoving ones — trees, mountains, stones. It is so subtle that the senses cannot detect it.
And it is both far away and very near. This is not a contradiction. Something that pervades everything is simultaneously the most distant thing and the most intimate. Air is like this — we cannot grab it, yet it flows inside our own lungs with every breath.
