Abstract
The yoga system accepts the S nkhya metaphysics, the fundamental variation being that consciousness is held to be supreme. The goal to be achieved is to attain this final state of pure consciousness. All obstacles, mental and physical, are subjugated and transcended. The method is the development of concentration by controlling all thought modes. It starts by the purification of the body by the control of posture and breathing. The mind is purified by the rejection of hindrances to the development of concentration. Both require a mandatory practice of the ethical ideals prescribed. The final goal of sam dhi is not a post-mortem state but realisable here and now. Many extraordinary capabilities acquired due to concentration are mere hindrances which are to be discarded. The Yoga S tras are four in number and made up p d s (steps). Only the first two s tras are explained in a very sketchy manner.
