三、知息長短。修特勝者藉觀以調心，心既靜細，則照了漸明。若得麁住、細住及欲界定，定中暗障薄，即便覺息入出長短之相也。若對念處，猶屬身念處觀也。

3. Knowing the long and short breath. One who cultivates the superior stages relies on contemplation to harmonize the mind. Once the mind is tranquil and subtle, illumination gradually becomes bright. If one attains coarse abiding, fine abiding, and the desire-realm concentration, the dark obstacles within concentration are thin, and one immediately perceives the characteristics of the in-breath and out-breath being long or short. Correlated with the bases of mindfulness, it still belongs to the contemplation of mindfulness of the body.
