Aptavani 10 (P) has Param Pujya Dadashri's spiritual discourses on the description and properties of Antaskaran- i.e mann-buddhi-chitt-ahankar (mind-intellect-vision-ego) all four put together. What is it made of? How does it develop? What is the form of Antaskaran in animals, deities, humans, children, etc. Before realization of the Self (non-gnan state), there is oneness with Antaskaran and after realization of the Self (gnan state) one is free from Antaskaran and its phases. In the first part of Aptavani 10, Dadashri has discussed in detail about the mind, its nature and function. What is the cause of the numerous thoughts that arise in our mind? What happens when we try to control our thoughts? We experience that at times our thoughts make us restless or there are random thoughts which crop up. Dadashri has put forth the science based on which the mind functions and how it is essential to understand this science so that the Self can remain separate from the mind, and eventually the Self can attain liberation.
