大毘盧遮那成佛經疏 13.215

13.215

次同前自在天，舒右掌，其中指稍亞頭向裏，共頭指稍作烈形也。即普花天子印（手當胸前側之。次脫一天子印）。

Next, like the previous Maheśvara: extend the right palm, with the middle finger slightly pressing its tip inward, forming a slightly curved shape with the index finger. This is the Samantapuṣpa Devaputra mudrā (place the hand sidewise before the chest. Here the mudrā of one devaputra has fallen out).
