3.51

答曰：五名雖少，而行通諸禪。所以者何？一、阿那波那門者，此通至根本及特勝、通明等諸禪三昧；二、不淨觀門者，此通九想、背捨、超越等諸禪三昧；三、慈心門者，此通四無量等諸禪三昧；四、因緣門者，此通至十二因緣、四諦等慧行諸禪三昧；五、念佛門者，此通至九種禪及百八三昧。

Answer: Although the five names are few, their practices connect to all dhyānas. Why is this? 1. As for the gate of ānāpāna, this connects to the fundamental [dhyānas] as well as the sublime practices, penetrating clarity, and other dhyāna-samādhis; 2. As for the gate of contemplation of impurity, this connects to the nine notions, liberations, transcending, and other dhyāna-samādhis; 3. As for the gate of the mind of loving-kindness, this connects to the four immeasurables and other dhyāna-samādhis; 4. As for the gate of causes and conditions, this connects to the twelve causes and conditions, the four truths, and other dhyāna-samādhis of wisdom practice; 5. As for the gate of mindfulness of the Buddha, this connects to the nine kinds of dhyāna and the one hundred and eight samādhis.
