大毘盧遮那成佛經疏 2.62

2.62

第卅三「云何舞心？謂修行如是法，我當上昇種種神變」者，如世人支分散動說名為舞，神變亦爾，現種種未曾有事，令前人心淨悅眼。多是五通餘習者。若偏尚如是悉地方便願求，亦障淨心也。當念除蓋障三昧，心無散動，神通不起滅定而作加持神變，勿貪世間少驗，是所對治。

The thirty-third: "What is the dancing mind? It is practicing such teachings [thinking]: 'I shall ascend to various supernatural transformations.'" Just as the scattering and swaying movements of limbs in an ordinary person are called dancing, supernatural transformations are also like this: one manifests various unprecedented feats to gladden and delight the eyes of those before them. This mostly belongs to the residual habits of those possessing the five mundane superknowledges. If one is exclusively devoted to aspiring for such siddhi expedients, this also obstructs the pure mind. Recollecting the samādhi that eliminates hindrance-coverings, keeping the mind free from distraction, and performing adhiṣṭhāna supernatural transformations without rising from the concentration of cessation, while not coveting slight worldly efficacy, serves as its antidote.
