Icchāsutta
“Aṭṭhime, bhikkhave, puggalā santo saṁvijjamānā lokasmiṁ. Katame aṭṭha? Idha, bhikkhave, bhikkhuno pavivittassa viharato nirāyattavuttino icchā uppajjati lābhāya. So uṭṭhahati ghaṭati vāyamati lābhāya. Tassa uṭṭhahato ghaṭato vāyamato lābhāya lābho nuppajjati. So tena alābhena socati kilamati paridevati, urattāḷiṁ kandati, sammohaṁ āpajjati. Ayaṁ vuccati, bhikkhave: ‘bhikkhu iccho viharati lābhāya, uṭṭhahati ghaṭati vāyamati lābhāya, na ca lābhī, socī ca paridevī ca, cuto ca saddhammā’.
Desire
“Mendicants, these eight individuals are found in the world. What eight? First, when a mendicant stays secluded, living independently, a desire arises for material things. They try hard, strive, and make an effort to get them. But material things don’t come to them. And so they sorrow and wail and lament, beating their breast and falling into confusion because they don’t get those material things. This is called a mendicant who lives desiring material things. They try hard, strive, and make an effort to get them. But when they do not acquire material things, they sorrow and lament. They’ve fallen from the true teaching.
