Eternal bliss is great nirvana. Great nirvana is the fruit that manifests itself in the field of benefiting and converting others. This body is the uncreated dharma-body. The uncreated dharma-body is the body of ultimate equality. The body of ultimate equality is tranquillity.
Tranquillity is true reality.
True reality is dharma-nature. Dharma-nature is suchness. Suchness is oneness. Hence, whether with regard to the cause or to its fruition, there is nothing whatever that has not been fulfilled through Amida Tathagata's directing of virtue to beings out of the pure Vow-mind. Because the cause is pure, the fruit is also pure.
