Aptavani 10 (U) 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 second part of Aptavani 10, Dadashri has discussed in detail about the intellect, vision and the ego, their nature and functions. Sometime, we feel that our buddhi (brains) interfere in some of our decision-making rather than supporting it. Our Chitta diverts our attention or projects things that we want. Our Chitta psychologically clicks photographs of people/situations. Our ahankar (ego) prevent us from experiencing the Self and it yearns for respect and fame. There could be both positive and negative ahankar at work. Dadashri has put forth the science based on which Buddhi- Chitta-Ahankar functions and how it is essential to understand this science so that the Self can remain separate from these elements, and eventually the Self can attain liberation.
