2.21

Cross-legged sitting (跏趺) (The first [character] has the sound jiā. The second has the sound of the fanqie fǔ + wú [fū]. The Sancang states: 'Fū refers to the instep of the foot.' Zheng [Xuan]'s commentary on the Yili states: 'The top of the foot.' According to Yoga rituals, there are the posture for subduing Māra and the auspicious posture. The character jiā (跏) should properly be written simply as jiā (加). First placing the right instep on the left thigh, and then placing the left instep on the right thigh, causing the two soles to face upward: this is named the posture for subduing Māra. As for the auspicious posture, first place the left instep upon the right thigh, and understand the rest by analogy with the preceding. Thus the auspicious posture is superior, and the posture for subduing Māra is secondary).
