The dictionary has been prepared, drawing heavily from the Vedantasara. But, to understand the terms given here, some background is needed. This has been provided in the two essays give in part one. The first essay, The Advaita Vedanta Darsana, gives a brief history of the school and presents its essential teachings, including the later ramifications, in a nutshell. The second essay, Sadananda's Vedantasara, summarises the salient features of this work. The dictionary itself is given in part two.
Those who have succeeded in attaching or detaching their minds at will have succeeded in Pratyahara, which means gathering towards, checking the outgoing powers of the mind, freeing it from the thralldom of the senses. When we can do this, we shall really possess character; then alone we shall have taken a long step towards freedom. Before that, we are mere machines.
-Swami Vivekananda
