大毘盧遮那成佛經疏 3.7

3.7

經云「若害法住無緣，當得法無我無畏」者，即是無緣乘心，觀察法無我性，於心外有無影像智都無所得，心王自在覺本不生，得離法之扼縛，於法無我得蘇息處。若真言行者，於瑜伽道中心得自在用時，位與此齊也。

The sūtra says: 'If one destroys dharmas and abides in the unconditioned, one shall attain fearlessness regarding the selflessness of dharmas.' This is precisely the mind that mounts the objectless, contemplating the nature of the selflessness of dharmas. When outside the mind the cognition of existent or non-existent images is completely ungraspable, the king of the mind is sovereign and awakens to the originally unborn; freed from the choking bonds of dharmas, one attains a place of respite in the selflessness of dharmas. For a mantra practitioner, when their mind attains sovereign functioning in the path of yoga, their station is equivalent to this.
