(Sanskrit, meaning, "point of dissolution") Laya is from the Sanskrit root li, meaning "to dissolve," "to disintegrate," or "to vanish away."
“The point of matter where every differentiation has ceased.” - Blavatsky, The Secret Doctrine
In Yoga: "Laya is the state of mind when one forgets all the objects of senses and gets absorbed in the object of meditation. Laya enables one to have perfect control over the five Tattvas, mind and Indriyas. The fluctuations of mind will stop. The mind, body and Prana will be entirely subdued." - Swami Sivananda
