注大乘入楞伽經 5.225

5.225

明從初地至七地以還菩薩，要須入禪定正受，始能現作種種身，如意遍至而無障礙。言入三昧樂正受時，離諸妄心、寂然不動，心海常安不起識浪，知一切境界，唯自心現，本無所有，是故名為三昧樂正受意成身。經家好略，舉中三地意該前後，以明七地也。

This clarifies that bodhisattvas from the first bhūmi up to the seventh bhūmi must enter dhyāna samāpatti before they can manifest various bodies, reaching everywhere according to their intention without obstruction. Saying that when entering the samāpatti of the bliss of samādhi, they are free from all false thoughts and are quiescent and motionless; the ocean of the mind is ever peaceful without raising waves of consciousness; they know that all realms are only manifestations of their own minds, originally having no existence. Therefore it is named the mind-made body of the samāpatti of the bliss of samādhi. The sūtra compiler preferred brevity, citing the middle three grounds to encompass the preceding and succeeding, in order to clarify the seven grounds.
