大乘法界無差別論疏 1.13

1.13

Fifth, as for the gateway of non-obstruction: within the preceding four gateways, mind and object, principle and phenomena blend without obstruction into a single dependent origination, existing or ceasing with mastery, not hindering one another, and are taken as the substance of the teaching. This is because the sacred teachings cited in the preceding four gateways do not contradict one another, their meanings are not separate from one another, and the substance of dharmas is not dual. Consider and understand it accordingly.
