大毘盧遮那成佛經疏 2.62

2.62

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.
