分別功德論 3.2

3.2

佛告諸比丘者，佛大慈，欲令弟子具知念佛之義，猶父約誡語子孫欲令成就無復已，已專精念佛，觀如來形目未曾離，猶如阿難觀佛無厭、心念無已。時阿難背上生癰，佛命耆婆治阿難所患。耆婆白佛：「不敢以手近阿難背。」佛告耆婆：「但治勿疑。我自當與阿難說法，令其不覺痛。」如來令阿難熟視佛相好，佛為說：「如來身者金剛之數，不可敗壞，三千二百福功德所成。」阿難目視不惓、耳聽不厭、心念不散。時耆婆於阿難背上潰癰傅膏。佛問阿難：「汝覺背上痛不？」答曰：「不覺。」不覺痛者，由念佛故也。

"The Buddha told the monks" refers to the Buddha's great compassion: wishing to make his disciples fully understand the meaning of mindfulness of the Buddha, just as a father gives binding admonitions to his children and grandchildren wishing them to reach perfection without cessation, so that they will single-mindedly and diligently be mindful of the Buddha, observing the Tathāgata's physical form without their eyes ever leaving it—just as Ānanda observed the Buddha insatiably, his mind mindful without cease. At that time, a carbuncle grew on Ānanda's back, and the Buddha ordered Jīvaka to treat Ānanda's affliction. Jīvaka addressed the Buddha: "I dare not touch Ānanda's back with my hands." The Buddha told Jīvaka: "Just treat it and have no doubt. I myself will preach the Dharma to Ānanda to make him feel no pain." The Tathāgata had Ānanda gaze intently at the Buddha's marks and signs, and the Buddha explained to him: "The Tathāgata's body is of the vajra nature, indestructible, accomplished by three thousand two hundred merits." Ānanda's eyes gazed untiringly, his ears listened unsated, and his mind's contemplation did not scatter. At that time, Jīvaka incised the carbuncle on Ānanda's back and applied ointment. The Buddha asked Ānanda: "Do you feel pain on your back?" He replied: "I do not feel it." That he did not feel pain was due to mindfulness of the Buddha.
