" O nobly-born, when thou art driven [hither and thither] by the ever-moving wind of karma, thine intellect, having no object upon which to rest, will be like a feather tossed about by the wind, riding on the horse of breath. Ceaselessly and involuntarily wilt thou be wandering about. To all those who are weeping [thou wilt say], ‘Here I am; weep not.’ But they not hearing thee, thou wilt think, ‘I am dead!’ And again, at that time, thou wilt be feeling very miserable. Be not miserable in that way. "

― Padmasambhava , The Tibetan Book of the Dead
