Aptavani 13, available in 2 volumes, was first published in July 2002 in Gujarati language, by Atmagnani Dr. Niruben Amin.

It is especially intended for the Self realized Mahatmas of Akram Vignan to further progress as the Self to absolute Self Knowledge called keval Gnan. The first volume of Aptavani 13 contains comprehensive material through the compiled and edited satsang of Gnani Purush Dadashri; with the specific topic of prakruti, charge and discharge karma in detail, Seeing, Knowing as the Self; naturalness of the prakruti and the Self, and the Seer and the Knower.

Gnani Purush Dadashri introduced Akram Vignan to the world in 1962. It is the direct easy way to liberation from all problems a human being may encounter directly or in worldly life interactions; by first realizing the Self and then understanding and becoming free from the non-Self complex—prakruti. This is accomplished by understanding the prakruti, its creation, its nature and its reactions with others in the world. Understanding the exact role of cause karma or charge karma; and the consequent effect, or discharge karma, adds further clarity. All this and more is explained in just the right amount necessary, for the awakened one in Akram Vignan, by Dadashri.

Dadashri never wrote any book. The material presented in this Aptavani 13 Vol 1 was collected in various ways; including direct audio recordings, by Atmagnani Dr. Niruben Amin, who then compiled it in specific topics. Atmagnani Deepakbhai Desai helped her in this extensive work. The current offering in English is the first one for the world.
