The Dynamics of Subject-Consciousness in Sthiramati’s Triṃśikābhāṣya: Momentariness, the Dharma-body, and Return
摘要
This paper investigates the dynamic configuration of “consciousness (vijñāna)” as a religio-philosophical subject in Sthiramati’s Triṃśikābhāṣya (hereafter TrBh), a commentary on Vasubandhu’s Triṃśikā (hereafter Tr). Grounded in the doctrine of momentariness (kṣaṇika), it traces how subject-consciousness progresses toward non-being, achieves being in the mode of the dharma-body (dharmakāya), and ultimately re-engages within the framework of “non-being–being–return.” It then clarifies the evolution of subject-consciousness across two phases. In the mundane realm (Tr 1, 17), it manifests as the “[continuous] transformation of consciousness (vijñānapariṇāma)” and “conceptualization (vikalpa).” In the supramundane realm (Tr 26–30), it matures into “subject-mind devoid of objects (artharahitacitta),” “[practical] subject-consciousness (jñāna),” “[supramundane] subject-mind (citta),” “mind excluding [discrimination] (acitta),” “supramundane knowledge (jñānaṃ lokottaram),” “transformation of the basis (āśrayasya parāvṛtti),” “uncontaminated foundation (anāsrava-dhātu),” and “thought excluding [grasping] (acintya).” This process culminates in the dharma-body, understood not as an ontological departure but as a philosophical and structural reconfiguration. By establishing non-being–being–return as a structural model, the present study illuminates how the practicing subject realizes the Mahāyāna bodhisattva ideal of intentional return.
