3.41

Furthermore, the Ugraparipṛcchā-sūtra states that the Buddha said: "Householder, when a householder bodhisattva enters a Buddhist monastery or vihāra, he should stand outside the gate, focus his mind, and make a prostration, and only then should he enter the vihāra. He should think to himself: 'When will I be able to dwell in such a monastery, a place that leaves behind the dust and defilement?'"
