Pondering the causes of suffering and death, he investigates the twelve links of dependent origination to find that the misery of samsara originates in ignorance and further develops through grasping.
The practitioner contemplates the twelve interdependent links in reverse order: seeing bones in a cemetery, he reflects upon death (12th link) and understands that it follows old age, which itself is caused by birth (11th).
Birth results from the drive to exist (10th),
which arises from grasping (9th), which rises from craving (8th),
which arises from feeling (7th), which arises from contact (6th),
which arises from the six senses (
5th), which arise from name and form
(4th) which arise from consciousness
(3rd), which arises from karmic dispositions
(2nd), which arise from ignorance (1st).
Action and Fruit: Because he is practicing for his own, limited deliverance, the pratyekabuddha does not teach others verbally, but nonetheless inspires faith in them through the display of miracles, such as flying through the sky or transforming the upper half of his body into fire and the lower half into water, and so on.
Eventually he becomes an arhat.
