For times infinite, people at large are hassled to understand the reality of life. The base to the reality is "Who am I?" and "Who is the doer (karta)?" The secrets of "who does" and how the "world works" have been revealed in this Audio book by Param Pujya Dadashri, the Gnani Purush (the enlightened one). The world functions on the concept of "vyavasthit shakti" (appropriate powers). It is extremely crucial to understand vyavasthit shakti and how it works, to appreciate the science of the Self. Vyavasthit shakti means scientific circumstantial evidences, many circumstances combined together lead to a certain action/result. Param Pujya Dadashri has talked about who is the real doer, what is vyavasthit shakti, what is the role of this shakti, how our karmas cause certain effects. With such understanding on why things happen, neither will we blame anyone for something that goes wrong nor will we selfishly take credit of whatever good happens. This will help in keeping a balance and peace in life.
