[28] "And what, bhikkhus, is the origin of form (rūpa)? What is the origin of feeling (vedanā)? What is the origin of perception (saññā)? What is the origin of volitional formations (saṅkhārā)? What is the origin of consciousness (viññāṇa)? Here, bhikkhus, one delights, one welcomes, one remains holding on. And what does one delight in, welcome, and remain holding on to? One delights in form, welcomes it, and remains holding on to it. For one who delights in form, welcomes it, and remains holding on to it, delight (nandi) arises. Whatever delight there is in form, that is clinging (upādāna). With that one's clinging as condition, there is existence (bhava); with existence as condition, birth; with birth as condition, aging and death, sorrow, lamentation, pain, grief, and despair come to be. Such is the origin of this whole mass of suffering (dukkha).
One delights in feeling … One delights in perception … One delights in volitional formations … One delights in consciousness, welcomes it, and remains holding on to it. For one who delights in consciousness, welcomes it, and remains holding on to it, delight arises. Whatever delight there is in consciousness, that is clinging. With that one's clinging as condition, there is existence; with existence as condition, birth … Such is the origin of this whole mass of suffering.
This, bhikkhus, is the origin of form; this is the origin of feeling; this is the origin of perception; this is the origin of volitional formations; this is the origin of consciousness."
