In a triad of practice manuals collectively titled _The Process of Meditation_ (_Bhāvanākrama I, II, III_), the eight century Indian Buddhist philosopher Kamalaśīla singles out _vipaśyanā_ (insight meditation) to be of particular importance on the early stages of the Buddhist path. This paper provides a reconstruction of _vipaśyanā_ based on how it is depicted in that work. I make two primary claims. First, _vipaśyanā_ is a technique for facilitating the direct perceptual ascertainment of a select set of properties, and second, (...) it accomplishes this by reconditioning the practitioner’s conceptual habitation. I further enrich this reconstruction by suggesting a series of stages that a practitioner progresses through, based on a list of intrinsically and extrinsically epistemic cognitions that Kamalaśīla gives in his _Commentary on the Compendium on Reality_ (_Tattvasaṃgrahapañjikā_). I end the paper with a potential method to use during meditation for altering one’s conceptual habitation. Kamalaśīla does not explicitly state these claims, but they can be inferred based on the theories on cognition found in both Kamalaśīla’s other works as well as the works of the Pramāṇavāda philosophers who influenced him. This reconstruction of _vipaśyanā_ thus remains consistent with Kamalaśīla’s own philosophical commitments, and is, I argue, the best way to explain the cognitive function of _vipaśyanā_ given those commitments.
