3.42

又十住毘婆沙論云。在家菩薩若入佛寺。初欲入時於寺門外。五體投地應作是念。此是善人住處。行慈悲喜捨住處。是故須禮。若見諸比丘威儀具足。見已恭肅敬心禮拜。親近問訊。又自愛經云。時有國王詣佛所。遙見精舍下車却蓋。解劍脫履拱手直進。

Furthermore, the Daśabhūmika-vibhāṣā-śāstra states: "When a householder bodhisattva enters a Buddhist monastery, as he is first about to enter, outside the monastery gate he should throw his five limbs to the ground and generate this thought: 'This is the dwelling place of good people; it is the dwelling place of those who practice loving-kindness, compassion, sympathetic joy, and equanimity. For this reason I must pay homage.' If he sees the bhikṣus endowed with complete deportment, having seen them he should bow in prostration with a respectful and reverent mind, and draw near to inquire after their well-being." Furthermore, the Zi'ai jing states: "At that time a king went to the Buddha's place. Seeing the vihāra from afar, he descended from his chariot, put away his canopy, unbuckled his sword, took off his shoes, clasped his hands, and walked straight forward."
