Tukdam
In the Vajrayana tradition of Tibetan Buddhism, tukdam (Standard Tibetan: ཐུགས་དམ, Wylie: thugs dam) is a meditative state said to occur after clinical death, in which the body shows minimal signs of decomposition, retaining a lifelike appearance for days or even weeks. Practitioners are believed by Buddhists to be in a profound state of meditation, merging their consciousness with the Clear Light.
