大方廣圓覺修多羅了義經略疏 2.1254

2.1254

例於靜也。應云：如是初覺從於一身至一世界。靜即是體、是定；覺即是慧、是用。初觀成，不見自身之相，名一身靜。以身靜時當體是覺，名一身覺。世界亦然。

Analogous to stillness. It should be said: 'Such initial enlightenment extends from one's single body to an entire world.' Stillness is the substance, is samādhi; enlightenment is wisdom, is function. When the initial contemplation is accomplished, one does not see the marks of one's own body, which is called 'the stillness of one body'. Because when the body is still, its very substance is enlightenment, it is called 'the enlightenment of one body'. The world is also like this.
