 Ishvara is seated in the hearts of all beings, O Arjuna, spinning all beings mounted on a machine by maaya.

the universe is like a gigantic video game set in motion by Ishvara. This video game is maayaa, also known as Prakriti, which is comprised of the three gunaas. By itself, maaya is insentient, it cannot do anything on its own. The eternal essence reflected in maaya adds sentience to maaya, it injects life into maaya by becoming the individual soul, the jeeva. In this way, each jeeva loses its connection with the eternal essence, and is stuck in this massive machine, this massive video game known as maaya.

 
So then, how can the jeeva liberate itself from this never ending video game of maaya? Does the jeeva have a chance? Is there any such thing as free will, or are we just slaves of maaya? The clue lies in the fact that maaya is subservient to Ishvara. If we only rely on maaya, if we only spend our lives attached to the material world, we will never have a chance at liberation. But if we direct our efforts towards knowing the true nature of Ishvara, towards contacting Ishvara, there may be a shot at liberation. Fortunately, he is not in some remote heaven, he is seated within us.
