"Senchakushū," written by Honen Shonin, is a seminal text in Pure Land Buddhism that systematically outlines the principles and practices of the Pure Land path. The full title, "Senchaku Hongan Nembutsu Shū," translates to "A Collection of Selections on the Nembutsu of the Original Vow." This work is crucial for establishing the Pure Land School (Jodo Shu) as an independent tradition in Japan.

In this text, Honen emphasises the practice of nembutsu, the recitation of Amitabha Buddha's name, as the primary and most effective means for attaining rebirth in the Pure Land. He bases his teachings on the three core Pure Land sutras and the commentary by Shandao on the Amitāyurdhyāna Sutra, among other sources.

Honen argues that in the age of mappo, a period of declining Dharma, traditional Buddhist practices are less effective, and therefore, reliance on Amitabha's vow through nembutsu is the most suitable path for liberation. The text critiques the established Buddhist schools of the Nara and Heian periods, which led to controversy and opposition from traditionalists. Nonetheless, Senchakushū played a pivotal role in the development and spread of Pure Land Buddhism in Japan.
