佛頂尊勝陀羅尼經教跡義記 1.65

1.65

述曰：第六正顯受身。文中有四：初受畜生，第二受地獄苦，第三受人身，第四生貧賤。處胎無兩目，若欲廣說因緣，有婆羅門述善住過去因中於母起瞋得報，如別抄記。

The commentary says: Sixth, directly showing the bodies to be received. In the text there are four parts: first, receiving animal [bodies]; second, suffering the torments of hell; third, receiving a human body; fourth, being born poor and lowly. Lacking both eyes in the womb: if one wishes to explain the causes and conditions in detail, a certain brāhmaṇa recounted that because Susthita in the causal stage in the past gave rise to anger toward his mother, he received this retribution, as recorded in a separate note.
