阿弥陀佛为秘密法主
Āmítuófó Is [The] Secret Dharma Master
【释迦牟尼】佛言:「金刚手!阿弥陀佛、毗卢遮那佛,乃是三界中,秘密法主大阿闍梨,无相无性、不生不灭,虽住秘密,无秘密相,后阿闍梨亦须如是分明了知。若了知已,乃是住三摩地金刚莲花主, 具大悲心有大力者。」
[Śākyamuni] Buddha said, ‘Vajra-[In]-Hand [i.e. Vajrapāṇi; Great Power Arrived Bodhisattva (大势至菩萨)]! Amitā Buddha [i.e. Āmítuófó] [and] Vairocana Buddha, thus are [the] three realms within, [their] secret Dharma Masters [and] Great Ācaryas [i.e. Spiritual Teachers and/or Preceptors], without form [and] without nature, not arising [and] not ceasing, although abiding [in] secret, without secret forms, [whom] later Ācaryas likewise must thus distinctly understand [and] clearly know. If clearly knowing [them] already, thus are those abiding [in] Samādhi’s Vajra Lotus Flower Masters, [who] possess Great Compassion’s mind [and] have Great Power.’
