Brahman

The Absolute is a generic name for whatever (or whoever) you think is the most powerful or fundamental or most evolved thing in the Cosmos (the total of the material and spiritual super-universe which may contain many sub-worlds and many parallel universes).

So, the Absolute may mean:
 * The God
 * The Tao
 * Your gods, such as Maat
 * The Nature
 * The Brahman
 * The Cosmic
 * The Primium Mobile
 * Whatever you believe is the most important thing in the Cosmos.
