Brahman (ब्रह्मन्) is a Hindu/Vedic term syncretic with the LP concept, god with a little "g" and with the wider Fabric of Consciousness in toto. As syncretic with god with a little "g", it refers to the original instantiated monad, the original spark of self-awareness which, because it was bored, unfolded/created all of physical creation. When referring to The Fabric, it refers to the Fabric in totality.
" Brahman connotes the highest Universal Principle, the Ultimate Reality in the universe. In major schools of Hindu philosophy, it is the material, efficient, formal and final cause of all that exists. It is the pervasive, genderless, infinite, eternal truth and bliss which does not change, yet is the cause of all changes.

In the Upanishads, it has been variously described as Sat-cit-ānanda (truth-consciousness-bliss) and as the unchanging, permanent, highest reality."
