The true success of human life lies in attaining inner peace and ultimately realizing one's true Self. In this journey, the greatest obstacle is our antahkaran (internal functioning mechanism in every human being composed of the mind, the intellect, the chit and the ego), and it is also our greatest tool. It is essential for our spiritual progress to understand how the four components of the antahkaran - the mind, the intellect, the chit, and the ego, function, and how they relate to one another. In this audio book, Param Pujya Dadashri, in an extremely simple, natural and example based style has explained in detail these four aspects of the antahkaran. Generally, we do use these terms, but we are mostly unaware of their true nature, their functioning, and the subtle distinctions between them. Dadashri provides explicit knowledge about the inner workings, the real form, and the location of these four components within our body. In particular, the audio book also sheds light on the difference between the antahkaran of animals and humans, the antahkaran of a child, the development of antahkaran in humans, and the means for its purification.
