大毘盧遮那成佛經疏 11.18

11.18

The sūtra says: "Those possessed of virtue and auspiciousness / Offer it in turn": having attained accomplishment, one carries it to the ten directions, offering it at will to the buddhas of the ten directions. For the buddhas, as well as the ācārya and companions, each has their share and procedure; this should be inquired into further. As for "The substance accomplished by mantra / Is called a siddhi": if one attains such accomplishment, it is called conceptual accomplishment. Because matters like these substances are still dharmas of accomplished signs, they are called conceptual accomplishment. As for "By means of conceptual substances, / One accomplishes the non-conceptual": dependent on the conceptual, one attains non-conceptual accomplishment. This ability to conceptualize serves as the cause. Attaining the non-conceptual fruit by relying on the conceptual means that, although the unconditioned, signless, inconceivable, and undefiled fruit is not accomplished by causes, yet with the conceptual as the cause, one nevertheless accomplishes this unobtainable and unconditioned fruit.
