The Avatamsaka Sutra, which is described by D.T. Suzuki as "the epitome of Buddhist thought, Buddhist sentiment and Buddhist experience," consists of eighty-one fascicles, divided into forty chapters. The chapter on "The Practices and Vows of the Bodhisattva Samantabhadra," the last and best-known chapter, represents the essence of Bodhisattva practice.
Precisely because these practices and vows contain the right causes of Buddhahood as well as the pure conditions for rebirth in the Pure Land, the ancients have also excerpted several passages and incorporated them in the daily liturgy of the faithful.
During his lifetime, Elder Master Yin Kuang frequently lectured on this chapter to encourage Pure Land practice and to demonstrate that rebirth in the Western Land is the common vow of the Bodhisattvas in the Ocean-Wide Avatamsaka Assembly. (Master Thich Tri Tinh.)
