Lecture Notes on the Sūtra of the Collection of the Father and Son (Pitāputrasamāgamanasūtra) (43)

原文：大王。云何身内风界。轻动等相。谓此内风。或时上行。或时下行。或住腹间。或胁或背。或发瘾胗。或聚成块。或如刀裂。或如针刺。出入息等。遍满身支。

释：Great King, what are the signs of the lightness and movement of the wind element within the body? They are the winds within the body that move from below upward; or from above downward; or from left to right and from right to left; or that dwell in the abdomen, the flanks, or the back; or that trigger rashes and swell into lumps; or that cause the body to feel pain like being cut by a knife or pricked by needles; as well as the winds of the breath moving in and out of the body—these kinds of winds pervade the limbs of the body.
