六妙法門 1.69

1.69

復有行者於數息中，證空靜定，以覺身心寂然，無所緣念。入此定時，雖復淺深有殊，而皆是空寂之相，當知於數息中，證止門禪定也。

Furthermore, there is a practitioner who, while counting breaths, realizes an empty and tranquil absorption, by which he senses that body and mind are serene, without any cognitive object or thought. When entering this absorption, although there are differences of depth, they are all marks of emptiness and tranquility; one should know that while counting breaths, he realizes the dhyāna absorption of the gate of cessation.
