Yo, bhikkhave, ime dhamme evaṁ saddahati adhimuccati, ayaṁ vuccati ‘saddhānusārī …pe… sambodhiparāyano’”ti. Catutthaṁ.

At Sāvatthī. “Mendicants, eye contact is impermanent, decaying, and perishing. Ear contact, nose contact, tongue contact, body contact, and mind contact are impermanent, decaying, and perishing. Someone who has faith and confidence in these teachings is called a follower by faith. …”
