What is "prakasa"

Prakāśa is a concept of Kashmir Shaivism translated by various authors as "light", "splendour", "light of consciousness" (identified with Śiva) (Swami Lakshman Joo), "luminous and undifferentiated consciousness" (Paul E. Murphy) or "primordial light beyond all manifestations" (Paul Muller-Ortega). Fellow Tantric practitioners Tibetan Buddhists practice Clear Light yoga based on a similar concept.

Prakāśa is considered supreme, ultimate, unsurpassable, but as such it cannot be described as pure transcendence, because even though it is above all, it is still present in the manifestation, in every aspect of it. Thus prakāśa is said to be both transcendent and immanent.
