7.22

二空 (Examining the Yoga Vidyādhara rituals, forming the various mudrās uses the five wheels and ten pāramitās; the five wheels are earth, water, fire, wind, and space/emptiness; each of the two hands takes the little finger as the beginning, rising in sequence through the wheels; the sūtra saying "join the two emptinesses" means joining and standing upright the two thumbs; the sūtra wrote 二腔, pronounced 苦 + 江 [qiāng], which is the character for the carcass/ribs of a sheep (yángqiāng), a scribal error; it greatly violates the meaning of the sūtra).
