And in 3 of "Yushikiron" (a Buddhism scripture written by an Indian priest from four to five centuries), it says, 'When one is just about to die, a line separating the hot part and cold part gradually appears on the body to show whether one is good-natured or evil-natured.'
また『唯識論』3には「叉将死時。由善悪業下上身分冷触漸起」とある。
