“Perfection” or “accomplishment.” In the yogic scriptures, this term designates either supreme spiritual liberation or a paranormal power. Paranormal powers represent an opening to Universal Shakti (non-personal energy). Often the practice of tapas (austerities) is a way to generate siddhis. In Tantra Yoga, Hatha Yoga, and Raja Yoga, siddhis are considered a consequence of the spiritual process. In Jnana Yoga, they are seen as simple illusions that should also be transcended. From the perspective of authentic spiritual practice, they should never be a goal in themselves.
