藏中有大方等大集賢護經、跋陂經，並與般舟同本異譯，專說現在佛悉在前立三昧，九十日中觀想稱誦彌陀。摩訶止觀常行三昧所準之經也。

The canon contains the Mahāvaipulya Mahāsaṃnipāta Bhadrapāla Sūtra and the Bapo Sūtra, which are both different translations of the same text as the Pratyutpanna. It specifically teaches the samādhi in which the present Buddhas all stand before one, contemplating and reciting [the name of] Amitābha for ninety days. It is the sutra upon which the constantly walking samādhi of the Mohe zhiguan is based.
