The graduated path to enlightenment (lamrim)

In 1042 the Bengali master Atisha arrived in western Tibet at the invitation of King Jangchub O, who wanted a guide that would stop translators and yogis from treating sutra study and tantric practice as rival paths pulling students in opposite directions. Atisha's answer was the Lamp for the Path to Enlightenment, a text of roughly seventy verses that sorted the entire Buddhist teaching by the scope of the practitioner rather than by school or scripture: those seeking only a fortunate rebirth, those seeking their own liberation from rebirth altogether, and those seeking full buddhahood for the sake of every being. Three and a half centuries later Tsongkhapa took that same three scope frame and expanded it into the Lamrim Chenmo, the Great Treatise on the Stages of the Path, completed in 1402, walking a reader from the most basic reflection on mortality up through the perfections and into tantra as a capstone built on that foundation rather than a shortcut around it. John Powers' survey of Tibetan Buddhism describes the lamrim genre that followed as the tradition's own solution to a practical problem, how to teach decades of scripture to one student in an order that will not strand them halfway.

The lamrim's insistence on sequence has a specific historical opponent, not just a philosophical one. Tibetan tradition dates the argument to a debate held at Samye monastery in the late eighth century between the Indian scholar Kamalashila, representing a graduated path through analysis and accumulated merit, and the Chinese Chan teacher known in Tibetan sources as Hashang Moheyan, who taught that thought itself was the obstacle and that non-conceptual insight required no sequence of preparatory steps at all. Tibetan royal and monastic histories record the king ruling in Kamalashila's favor, and Kamalashila is said to have written a set of Stages of Meditation treatises setting out the gradualist case in the debate's aftermath. Modern scholarship treats the reported outcome with real caution, since every surviving account of who won was written by the winning side, but the debate's memory did the cultural work regardless of what actually happened in the room: it gave later Tibetan scholasticism, and Tsongkhapa after it, a founding story in which the graduated path had already met its sudden rival directly and could name exactly what it was arguing against. Manuscripts recovered from the Dunhuang caves complicate the neat resolution the Tibetan sources report: a Chinese-language account among that material claims Moheyan's own position won imperial approval, the reverse of what later Tibetan historiography preserved. Twentieth century scholarship built around those manuscripts, most influentially Paul Demieville's study of the episode, treats the contradiction itself as evidence the debate's outcome was contested from close to the start rather than only debated by modern historians centuries afterward.
