Siddha

A Siddham in Tamil means "one who is accomplished" and refers to perfected masters who, according to Hindu belief, have transcended the ahamkara (ego or I-maker), have subdued their minds to be subservient to their Awareness, and have transformed their bodies (composed mainly of dense Rajo-tama gunas) into a different kind of body dominated by sattva. This is usually accomplished only by persistent meditation.
