三彌勒經疏 1.97

1.97

From the text of the sūtra where it says, "Sitting cross-legged" onwards, this is the third [section], [explaining] the physical posture of his decease. "Crossing" means interlinking; "legged" means overlapping. Because Śākyamuni's conditions had come to an end, he entered nirvāṇa on his right side with his hand pillowing his head. Because Maitreya's defilements had not yet come to an end, the two sages differed.
