Abstract

Psi experiences, or siddhis, are one among many varieties of human experiences reported from ancient times across cultural and geographical boundaries. The data and theories from psi research inform philosophical debates on the nature of time, causality, information and their implications for the free-will–determinism debate. In this article we present an overview of theoretical approaches of psi research, and the varieties of siddhis mentioned in classical Indian literature. Further, we examine siddhis in relation to the findings from contemporary psi research, with particular reference to informational psi, along the dimensions of training, personality, and meditation.
