淨土論 3.43

3.43

Answer: As Dhyāna Master Daochuo discovered upon examining the scriptural passages, if one can simply engage in mindfulness of the Buddha single-mindedly and undisturbed, reaching one million times or more, one is definitely assured rebirth in the Pure Land. Furthermore, Dhyāna Master Daochuo, relying on the Smaller Amitābha Sūtra's [practice of] mindfulness of the Buddha for seven days, calculated [it to amount to] one million times. Therefore, that the Mahāsaṃnipāta Sūtra, Bhaiṣajyaguru Sūtra, and Smaller Amitābha Sūtra all encourage mindfulness of the Buddha for seven days makes this meaning clear.
