Yantra is a machine, any machine that is used for the purpose to bring about a certain function. In ‘Tantra’ too, there are yantras, which satisfy almost the same function as the machine. They are those diagrams which are used to bring about certain action, in the outer as well as the inner sphere. The process or the science of bringing it about is called ‘Tantra’. The switch by which the energies are gathered and used in tantra, to activate the yantra, is called ‘mantra’. Tantra, thus, is a very practical science and is not merely theoretical.
Sri M, as Sri Mumtaz Ali is popularly known, is a social activist, educationist and a crusader for inter-religious harmony with a deep knowledge of world religions. At the young age of 19, he travelled to the Himalayas from Kerala, and there he met and lived for several years with a ‘real-time’ yogi, Babaji. This is part of his unique persona, given his non-Hindu birth and antecedents. The bonus for those interested in the secrets of yoga, meditation and sankhyan metaphysics is that Sri ‘M’ is amongst us and is easily reachable. He leads a normal life, married with two children, wears no special robes and conducts himself without pomp or paraphernalia. He needs no precondition to help people, nor does he have any formula for masses. Sri M lives in a valley on the outskirts of Madanapalle in Andhra Pradesh but is often on the move travelling far and wide for lectures.
