首楞嚴義疏注經 6.77

6.77

Asuras are ugly in form and full of arrogance. Doubtful spirits (kiṃnara) resemble humans while bearing horns. Python forms (mahoraga) are of the kind that crawl on their bellies like field crickets. Because they often violated precepts while practicing slight generosity, they fell into these destinies. Each vows to transcend their class, and all are accorded with their desires.
