When a person has entered completely into the Pure Land of happiness, he or she immediately realizes the supreme nirvana; he realizes the supreme enlightenment. Although the terms differ, they both mean to realize the enlightenment of the Buddha who is dharma-body. As the true cause for this realization, Bodhisattva Dharmakara gave us the Vow of Amida Buddha; this is known as directing virtue for the sake of our going forth in birth. This Vow of directing virtue is the Vow of birth through the nembutsu. To entrust oneself wholeheartedly to the Vow of birth through the nembutsu and be single-hearted is called wholehearted single practice. In terms of the Tathagata’s two forms of giving, true shinjin is to entrust oneself to the Vow of giving and be single-hearted; this shinjin arises from the working of the honored ones, Sakyamuni and Amida.
Respectfully.
