Toh 1540A Commentary on the Four Lamps

Exposition of "A Commentary on the Four Lights" (Ullocatuṣṭayaṭīkā)

Context

"A Commentary on the Four Lights" is an exegetical work belonging to the Tengyur — the Northern Transmission, representing the Mahayana tradition of Tibetan Buddhism. This work is related to the fields of Abhidharma and Pramāṇa, two important foundations of Buddhist philosophy.

Within the context of Mahayana practice in the Northern Transmission, the "Four Lights" are not merely a mythic image but also symbolize advanced stages of luminous wisdom. This commentary was composed to clarify profound aspects of the Dharma, helping monastics grasp the excellent meaning behind traditional images and ideas.

Main Content

This treatise focuses on explaining the "four lights" — a central concept in Buddhist practice. Each light represents a dimension of luminous wisdom (prajñapti) and the cognition of truth.

The first is the light of clear knowledge (vidyā), which brings the practitioner to clarity concerning the nature of dharmas. The second is the light of the purified mind (citta-śuddhi), which purifies the mind of fundamental obscurations. The third is the light of liberation (mokṣa), which points directly to the ultimate goal of practice. The fourth is the light of bodhicitta, the mind that gives rise to the aspiration to liberate beings — the distinguishing feature of the Mahayana.

This commentary does not stop at empty theory, but includes concrete methods of practice, the correlation of these lights with the levels of cultivation, and the progression on the bodhisattva path. It emphasizes that these lights are not separate, but are unified, forming a complete system of liberation.

Practical Meaning

In the context of Mahayana practice in the Northern Transmission today, "A Commentary on the Four Lights" reminds us that practice is not merely a personal effort to realize an undifferentiated human state.
