[195] Then several bhikkhus approached the Blessed One; having approached and paid homage to the Blessed One, they sat down to one side. Sitting to one side, those bhikkhus said this to the Blessed One: "Venerable sir, the Venerable Tissa, the son of the Blessed One's paternal aunt, informs several bhikkhus thus: 'Friends, my body has become as if drugged (madhurakajāto); the directions do not appear clear to me; the teachings (dhammā) no longer spring to mind for me; dullness and drowsiness (thīna-middha) persist obsessing my mind (citta); I lead the holy life without delight; and I have doubt (vicikicchā) about the teachings.'"
Then the Blessed One addressed a certain bhikkhu: "Come, bhikkhu, address the bhikkhu Tissa in my name, saying: 'Friend Tissa, the Teacher calls you.'" "Yes, venerable sir," that bhikkhu replied to the Blessed One, and he approached the Venerable Tissa; having approached, he said this to the Venerable Tissa: "Friend Tissa, the Teacher calls you." "Yes, friend," the Venerable Tissa replied to that bhikkhu, and he approached the Blessed One; having approached and paid homage to the Blessed One, he sat down to one side. The Blessed One said this to the Venerable Tissa as he sat to one side: "Is it true, Tissa, that you informed several bhikkhus thus: 'Friends, my body has become as if drugged … and I have doubt about the teachings'?" "Yes, venerable sir."
"What do you think, Tissa: in one who is not free from lust for form (rūpa), not free from desire, not free from affection, not free from thirst, not free from fever, not free from craving (taṇhā) — through the change and alteration of that form, do sorrow, lamentation, pain, grief, and despair arise?" "Yes, venerable sir." "Good, good, Tissa! So it is, Tissa, for one not free from lust for form. … for feeling (vedanā) … for perception … in one not free from lust for volitional formations … through the change and alteration of those volitional formations, do sorrow, lamentation, pain, grief, and despair arise?" "Yes, venerable sir." "Good, good, Tissa! So it is, Tissa, for one not free from lust for volitional formations. In one who is not free from lust for consciousness, not free from desire, not free from affection, not free from thirst, not free from fever, not free from craving — through the change and alteration of that consciousness, do sorrow, lamentation, pain, grief, and despair arise?" "Yes, venerable sir." "Good, good, Tissa! So it is, Tissa, for one not free from lust for consciousness."
