[191] On one occasion the Blessed One was dwelling at Vesālī, in the Great Wood, in the Hall with the Peaked Roof. Then Ugga the householder of Vesālī approached the Blessed One … Seated to one side, Ugga the householder of Vesālī said this to the Blessed One: "What, venerable sir, is the cause, what is the condition, whereby some beings here do not attain final Nibbāna (parinibbāna) in this very life? And what, venerable sir, is the cause, what is the condition, whereby some beings here attain final Nibbāna in this very life?"
"There are, householder, forms cognizable by the eye — desirable, lovely, agreeable, pleasing, connected with sensuality, provoking lust. If a bhikkhu delights in that, welcomes it, and remains holding to it, then for him — delighting in it, welcoming it, remaining holding to it — consciousness becomes dependent upon that, with clinging (upādāna) to that. A bhikkhu with clinging, householder, does not attain final Nibbāna. … There are, householder, tastes cognizable by the tongue … There are, householder, mental phenomena (dhammā) cognizable by the mind — desirable, lovely, agreeable, pleasing, connected with sensuality, provoking lust. If a bhikkhu delights in that, welcomes it, and remains holding to it, then for him — delighting in it, welcoming it, remaining holding to it — consciousness becomes dependent upon that, with clinging to that. A bhikkhu with clinging, householder, does not attain final Nibbāna. This, householder, is the cause, this is the condition, whereby some beings here do not attain final Nibbāna in this very life."
