In the Mahāyānasaṅgraha, Asaṅga refers to the spiritual awakening called āśrayaparāvṛtti, the conversion of the individual ontological base. For the sake of this awakening, one must hear Buddha’s instruction in the beginning. By hearing that, śrutavāsanābīja, the spiritual potential for awakening, is impressed on one’s ontological base called dharmakāya, the primordial body of Buddha. From this potential, manojalpa (mind’s talk), the Buddhist rational consciousness, occurs. And from this consciousness, nirvikalpajñāna, the Buddhist wisdom without differentiation, occurs. This wisdom leads us to āśrayaparāvṛtti which converts the ontological base from ālayavijñāna, our secular ontological base, to dharmakāya. After this awakening, we obtain sarvajñajñāna (omniscient wisdom), the highest Buddhist wisdom. On tracing this kind of process of wisdom’s development, I make clear the structure of āśrayaparāvṛtti in the Mahāyānasaṅgraha.
