[87] At Sāvatthī. There [the Blessed One said]: …
"Bhikkhus, dwell with yourselves as an island, with yourselves as a refuge, with no other refuge; with the Dhamma as an island, with the Dhamma as a refuge, with no other refuge. Bhikkhus, when you dwell with yourselves as an island, with yourselves as a refuge, with no other refuge, with the Dhamma as an island, with the Dhamma as a refuge, with no other refuge, it should be thoroughly investigated (yoniso): 'From what are sorrow, lamentation, pain, grief, and despair born? From what are they produced?'
"And from what, bhikkhus, are sorrow, lamentation, pain, grief, and despair born? From what are they produced? Here, bhikkhus, the uninstructed worldling, who has no regard for the noble ones, who is unskilled in the Dhamma of the noble ones and undisciplined in the Dhamma of the noble ones, who has no regard for good persons, who is unskilled in the Dhamma of good persons and undisciplined in the Dhamma of good persons, regards form as self, or self as possessing form, or form as in self, or self as in form. That form of his changes and becomes otherwise. With the change and alteration of form, there arise in him sorrow, lamentation, pain, grief, and despair.
"He regards feeling (vedanā) as self, or self as possessing feeling, or feeling as in self, or self as in feeling. That feeling of his changes and becomes otherwise. With the change and alteration of feeling, there arise in him sorrow, lamentation, pain, grief, and despair.
"Perception … He regards volitional formations as self … He regards consciousness as self, or self as possessing consciousness, or consciousness as in self, or self as in consciousness. That consciousness of his changes and becomes otherwise. With the change and alteration of consciousness, there arise in him sorrow, lamentation, pain, grief, and despair."
