Viññāṇasutta
Sāvatthinidānaṁ. “Yo, bhikkhave, cakkhuviññāṇasmiṁ chandarāgo, cittasseso upakkileso. Yo sotaviññāṇasmiṁ … yo ghānaviññāṇasmiṁ … yo jivhāviññāṇasmiṁ … yo kāyaviññāṇasmiṁ … yo manoviññāṇasmiṁ chandarāgo, cittasseso upakkileso. Yato kho, bhikkhave, bhikkhuno imesu chasu ṭhānesu cetaso upakkileso pahīno hoti, nekkhammaninnañcassa cittaṁ hoti. Nekkhammaparibhāvitaṁ cittaṁ kammaniyaṁ khāyati, abhiññā sacchikaraṇīyesu dhammesū”ti.
Consciousness
At Sāvatthī. “Mendicants, desire and greed for eye consciousness, ear consciousness, nose consciousness, tongue consciousness, body consciousness, or mind consciousness is a corruption of the mind. When a mendicant has given up mental corruption in these six cases, their mind inclines to renunciation. A mind imbued with renunciation is said to be fit for work regarding anything that can be realized by insight.”
