Abstract
This paper surveys the key terms śaktipāta and samāveśa (both of which refer to religious experience) in the primary sources of Tantric Śaivism over several centuries of textual development, building up a theory as to their range of meanings. It specifically focuses on their usage by Abhinavagupta (Kāshmīr, 10th century) by presenting a complete translation of chapter 11 of his Tantrasāra. The paper thus serves to (a) illuminate the nature of spiritual experience and the qualifcations for religious praxis in Śaivism, (b) give insight into the worldview of the Tantric Śaivas, and (c) help in pinpointing a specific and significant issue in the phenomenological study of religion generally.
