首楞嚴義疏注經 8.324

8.324

引事驗也。身輕清、顧雄毅、夢飛舉、聖境現、輕身命，此五皆是殊勝氣色，由想故有也。毅，果敢也。

This adduces circumstances as verification. The body being light and clear, the glance commanding and resolute, flying upward in dreams, the sacred realms appearing, and making light of one's body and life—these five are all extraordinary auras and dispositions, existing because of thought. Resolute (yi) means decisive and bold.
