What is Pralaya?
Pralaya is the Sanskrit term for cosmic dissolution in Hindu cosmology. It names the period of reabsorption that follows every kalpa, the day of Brahmā, in which the manifest universe is withdrawn back into unmanifest potentiality. The word joins pra- (forward, away) with the root lī (to dissolve, to melt, to become absorbed). What creation unfolds, pralaya refolds. The cycle is then complete, and a new day of Brahmā begins.
Pralaya vs adjacent concepts
Pralaya is not the same as *saṃsāra*. Saṃsāra is the ongoing wheel of birth, death and rebirth within a world cycle. Pralaya is the end of the world cycle itself — the point at which the wheel stops, folds away, and waits before turning again. The *karma* accumulated before a pralaya is not erased by it. The tradition holds that tendencies (saṃskāras) that drive rebirth persist in seed form through the dissolution and unfold again in the next creation. *Māyā*, the creative power that veils the unmanifest as a world, is what pralaya withdraws. *Brahman* itself, the unchanging ground, is untouched by dissolution. Pralaya is not final annihilation. It is an interval.
The grades of dissolution
The Purāṇas, principally the Viṣṇu Purāṇa and the Bhāgavata Purāṇa, classify pralaya into several grades, though the exact enumeration varies between texts. The most widely cited forms are three. Naimittika (occasional) pralaya is the dissolution at the close of each kalpa, when Brahmā rests and the three worlds are consumed by fire before the next day begins. Prākṛtika (elemental) pralaya is the dissolution at the close of Brahmā's entire life, when even the raw elements and the cosmic intellect dissolve back into *prakṛti*, the root of matter. Ātyantika (absolute or individual) pralaya is not a cosmic event at all. It is the liberation of a single jīva, the absorption of the apparent individual into *Brahman*, which is what the tradition calls *mokṣa*. Some texts add nitya (constant) pralaya, the moment-by-moment dissolution that occurs in sleep and in the small extinctions of ordinary life.
The deepest reset the cosmological system describes is the mahāpralaya, the great dissolution at the end of Brahmā's life. Even Brahmā, the creator, is himself a created being with a finite lifespan. When that life ends, *prakṛti* and *puruṣa*, matter and pure consciousness, stand apart before a new Brahmā arises and the cycle begins again. The time scales are vast. Brahmā's one hundred divine years, reckoned in human time, runs to trillions of solar years.
In the index
The pralaya framework appears mainly through teachers working in the Hindu lineage. Sadhguru's longer-form lectures return to the kalpa and yuga framework as a way of orienting the practitioner inside a cycle far longer than personal memory. His book *Inner Engineering: A Yogi's Guide to Joy* sets the same cosmological scaffolding beneath its practical curriculum. Paramahansa Yogananda's *Autobiography of a Yogi* carries the kriyā-yoga lineage's account, in which the creation and dissolution of universes is part of the lived reality of advanced states. In each case the point is not the number. It is the scale: the ordinary human life is a small event inside a much larger breathing.
What it isn't
Pralaya is not the end of the world in the Abrahamic sense. There is no final judgement and no permanent cessation. The dissolution is always followed by a new creation. It is also not nihilism. The *Advaita Vedānta* reading holds that *Brahman*, consciousness itself, is never dissolved. Only its appearances fold away. The tradition's claim is structural rather than historical. How literally the time scales should be read has been debated within the tradition and by modern interpreters. Some teachers treat the figures as precise cosmological data. Others read them as deliberate amplifications whose function is to dislodge the ordinary horizon of a single life and open the practitioner to a longer frame.
