Brahman is not contained in this world like say, if you have a bowl and you have got peas or fruit. It's not like the world is a cupboard in which many items are stored. The ultimate reality is not one type of reality, one existing thing among many existing things but it is the very existence of all of them. That unmanifest, this is Brahman, which is called the imperishable,. Is said to be the supreme goal attaining which they return not. Nastya Tzu Navinashyati is the next.
