Now, when those ascetics and brahmins speculate and theorize about the first beginning and the final end on these sixty-two grounds, all of them experience this by repeated contact through the six fields of contact. Their feeling is a condition for craving. Craving is a condition for grasping. Grasping is a condition for continued existence. Continued existence is a condition for rebirth. Rebirth is a condition for old age and death, sorrow, lamentation, pain, sadness, and distress to come to be.
