What does the word Brahman actually mean?

Sages say that it is ‘beyond verbal description’, but as a pointer they postulate Sat Chit Ananda which means Reality-Consciousness-Bliss. Brahman is not a God but an Almighty Great Power. It is the substrate of ‘All and Everything’, which means it contains the whole universe and holds it altogether. Brahman has two agents or adjuncts. First of all is Ishvara or Almighty God and Maya its delusionary power.
