When a pot is broken the space that was in it becomes one with space; so too when the limitation caused by the body and its adjuncts is removed the Sage, realized during life, shines as Brahman, becoming absorbed in Brahman he already was, like milk in milk, water in water, or oil in oil, and is radiant as the One Supreme Self. Thus, when the Sage who abides as Brahman, which is Pure Being, obtains his disembodied absolute state, he is never again reborn.

(Shankara(Adi Shankaracharya))
