THE ABSOLUTE

In Vedanta, Brahman is sometimes referred to as the Absolute, or Godhead, which is the Divine Ground of all being. 

Brahman is conceived as either impersonal ("without qualities"), or personal ("with qualities"), depending on the philosophical school.   For example, Advaita philosophy considers Brahman to be without form, qualities, or attributes, while Visishtadvaita and Dvaita philosophies understand Brahman as one with infinite auspicious qualities.

Brahman cannot be seen or heard but can be known intuitively.  This is to say that it cannot be known by empirical means, i.e. as an object of our consciousness, for it is our very consciousness and being.

It may be said, therefore, that moksha, liberation, does not mean to know Brahman intellectually.  What is meant is realizing "brahman-hood," actually grasping that one is and always was Brahman.  Indeed, in Advaita's view, a liberated human being is one who realizes Brahman as his or her own true self.

Generally, Vedanta rejects the notion of an evolving Brahman since Brahman contains within it all possible manifest phenomenal forms.
