釋門歸敬儀 2.81

2.81

言理發者，即是自心五陰、諸法本性無我，深知此要，名菩提心。故《淨名》云：「寂滅是菩提，離諸相故；假名是菩提，名字空故。」又如《問菩提經》云：「菩提相者，出三界過俗法，言語斷滅，諸發無發，是名發菩提心。」如是眾經例遣想，故名發心。

To speak of arousing it through principle: this means that the five aggregates of one's own mind and all phenomena are fundamentally non-self in nature; deeply knowing this essential point is called the bodhicitta. Therefore the Vimalakīrti Sūtra states: 'Quiescence is bodhi, because it is free from all marks; conventional designation is bodhi, because names are empty.' Furthermore, as the Sūtra on Questioning Bodhi states: 'The mark of bodhi transcends the three realms and goes beyond conventional phenomena; speech is cut off, and all arousals are non-arousal—this is called arousing the bodhicitta.' In this way, the various sūtras uniformly dispense with conceptualizations; hence it is called arousing the mind.
