大毘盧遮那成佛經疏 13.212

13.212

次無能勝明王印。右手如執蓮華印（風空指頭相捻，火指垂屈當中，地水指正竪即是也），直舒左手，五指向上而向外托之（指頭舒散也），其手稍令高於頭，即是也。其立如前鉢栗底（丁也反）哩也。

Next is the Aparājita Vidyārāja mudrā. The right hand forms the holding-a-lotus mudrā (the tips of the wind and space fingers pinch together, the fire finger is bent down in the center, and the earth and water fingers are held straight upright); extend the left hand straight, with the five fingers pointing upward and holding outward (the fingertips spread open), holding the hand slightly higher than the head—that is it. The standing posture is the pratyālīḍha described earlier.
