維摩經略疏 5.95

5.95

From "For what reason" down to "standing": second, recounting the reasons for being unworthy. Because the Buddha had a slight illness and needed to use cow's milk, [Ānanda] held his bowl and went to beg, and was thus rebuked. Why is this? The Tripiṭaka only clarifies the birth body as the real Buddha, and does not speak of the three bodies and three virtues of the Dharma-nature. The birth body has the nine afflictions—hunger, thirst, cold, heat, illnesses, and so forth—which is why when the body had a slight illness, it was necessary to use cow's milk. Ānanda did not know this was the Dharma-nature body and thought that having an illness was real; therefore he held his bowl to beg for milk. This is hearing much of the half-letter [teachings], not having heard that the vajra essence of the dharmakāya is eternally abiding and tranquil; because of this he was rebuked.
