淨名經集解關中疏 2.8

2.8

"Subduing the hosts of Māras, sporting with supernormal knowledges"—this [passage] praises the perfection of the merits of benefiting both [oneself and others]. Subduing Māras benefits others, and attaining liberation benefits oneself; this is the first. Kumārajīva says: "Transforming beings through supernormal knowledges is not ultimate reality, hence it is termed 'sport'. Furthermore, although supernormal knowledges are great, for me there is no difficulty, just like playing. Furthermore, skillfully entering, arising from, and dwelling in them with unfettered ease is like playing." Sengzhao says: "Roaming in supernormal knowledges to transform people is how he entertains himself."
