In this paper, I provide a philosophical analysis of Pāli texts that treat of a special kind of mental event called bhavaṅga citta. This mental event is a primal sentient consciousness, a passive form of basal awareness that individuates sentient beings as the type of being that they are. My aims with this analysis are twofold, one genealogical and reconstructive, the other systematic. On the genealogical and reconstructive side, I argue for a distinction between two kinds of continuity that are (...) at work in explaining the temporal structure of experience in Pāli Buddhist philosophy. Call these two forms of continuity ‘diachronic’ and ‘affective-motivational’ continuity, respectively. In my analysis of these two forms of continuity, I will focus on the coherence of bhavaṅga citta in its Abhidhammic context. My contention is that the commentarial account of bhavaṅga citta has the resources to explain diachronic continuity but struggles to give a fully workable account of affective-motivational continuity. I argue that the novel view of mental continuity offered by the early twentieth century Burmese monastic exegete Ledi Sayadaw offers another intriguing account of mental continuity, one that can help to explain affective-motivational continuity. Systematically speaking, in spelling out the dynamics of this distinction between types of mental continuity in connection with bhavaṅga, I offer a cross-cultural philosophical analysis of the deep structure of the mind and how affective processes below the threshold of ordinary habits of attention have a profound conditioning effect on our conscious relationship with the world.
