Both the Hesychast tradition of Eastern Orthodox Christianity and the Dzogchen (rdzogs chen) tradition of the Nyingma (rnying ma school) of Tibetan Buddhism refer to modes of awareness that lie outside the bounds of ordinary human cognition. Likewise, both traditions employ similar contemplative modalities to induce this awareness: mindful or neptic awareness, breath-control techniques, moral asceticism, repetition of prayer, etc. While much attention has been paid to the intersections of contemplative Christianity and Buddhism from the perspective of Western Christians interested in interfaith dialogue, very little literature has addressed similar intersections from the perspectives of Eastern Christianity. This paper will explore parallels between understandings of the "uncreated light" of theoria and theosis, and the clear light ('od gsal) of primordial awareness (rig pa), primarily through the lens of textual evidence from Orthodox ascetic manuals and Nyingma expositions on yogic practices. While acknowledging that each tradition's descriptions are conceptually and doctrinally non-reducible to one another, I still will argue that this is a concrete example of employing similar contemplative methods to circumvent the limitations of rational intellect, ultimately with the aim of guiding the practitioner closer to the experiential knowledge of a reality each tradition describes as ineffable. By examining this similarity in detail, I provide a basis for further, progressive inquiry into the intersections between the contemplative traditions of Tibetan Buddhism and Eastern Christianity.
