(Sanskrit) A compound word, formed of laya, from the root li, and the prefix pra. Li means "to dissolve," "to melt away," "to liquefy," as when one pours water upon a cube of salt or of sugar. The cube of salt or of sugar vanishes in the water — it dissolves, changes its form — and this may be taken as a figure, imperfect as it is, or as a symbol, of what pralaya is: a crumbling away, a vanishing away, of matter into something else which is yet in it, and surrounds it, and interpenetrates it. Such is pralaya, usually translated as the state of latency, state of rest, state of repose, between two manvantaras or life cycles. If we remember distinctly the meaning of the Sanskrit word, our minds take a new bent in direction, follow a new thought. We get new ideas; we penetrate into the arcanum of the thing that takes place. Pralaya, therefore, is dissolution, death.
There are many kinds of pralayas. There is the universal pralaya, called prakritika, because it is the pralaya or vanishing away, melting away, of prakriti or nature. Then there is the solar pralaya. Sun in Sanskrit is surya, and the adjective from this is saurya: hence, the saurya pralaya or the pralaya of the solar system. Then, thirdly, there is the terrestrial or planetary pralaya. One Sanskrit word for earth is bhumi, and the adjective corresponding to this is bhaumika: hence, the bhaumika pralaya. Then there is the pralaya or death of the individual man. Man is purusha; the corresponding adjective is paurusha: hence, the paurusha pralaya or death of man. These adjectives apply equally well to the several kinds of manvantaras or life cycles.
There is another kind of pralaya which is called nitya. In its general sense, it means "constant" or "continuous," and can be exemplified by the constant or continuous change — life and death — of the cells of our bodies. It is a state in which the indwelling and dominating entity remains, but its different principles and rupas undergo continuous and incessant change. Hence it is called nitya, signifying continuous. It applies to the body of man, to the outer sphere of earth, to the earth itself, to the solar system, and indeed to all nature. It is the unceasing and chronic changing of things that are — the passing from phase to phase, meaning the pralaya or death of one phase, to be followed by the rebirth of its succeeding phase. There are other kinds of pralayas than those herein enumerated. [Occult Glossary by G. de Purucker]
