According to the belief of the Tibetans, that is considered an untimely death, which, in opposition to the ordinary course of nature, is accelerated by evil spirits, such as Sringan, Dechad, Jungpo, and others. As a consequence of premature decease, the "Bardo," is prolongated. This is the middle state between the death and the new re-birth, which does not follow immediately, but there exists an interval, which is shorter for the good than for the bad. The prolongation of this intermediate state is considered as a punishment caused by evil spirits who have only power over sinful men.
