Siddhi (Sanskrit सिद्धि, Tibetan དངོས་གྲུབ་ ngödrub, meaning “accomplishment” or “realization”) refers in yoga, tantra, and Vajrayana Buddhism to the results or attainments of spiritual practice. Siddhis are not techniques but effects—natural expressions of a mind aligned with deeper layers of reality.
Symbolically, siddhis represent the permeability of reality once fixation on a separate self dissolves. Abilities such as clairvoyance, healing, extraordinary perception, or influence over circumstances are not regarded as miracles but as by‑products of altered perception. Reality is no longer experienced as solid, but as responsive.
Esoterically, traditions distinguish between ordinary siddhis (special capacities, insights, energetic effects) and the supreme siddhi, which is complete liberation. This highest siddhi is unspectacular yet absolute: the stable recognition of the nature of mind. All other siddhis are considered secondary and potentially distracting.
In tantric lore, siddhis are closely associated with the Mahasiddhas, realized masters whose unconventional lives demonstrate that true accomplishment is not bound by social convention. Siddhi here signifies not power, but freedom in action.
