Everything is the Supreme Being, which is Existence – consciousness - bliss, and ‘I am That’. By constantly cultivating this pure thought, get rid of impure thoughts. Then discarding even that thought and always inhering in the state of fullness, you will become the non-dual and undifferentiated Supreme Being and attain liberation.
As long as you have attachment to the body and attachment to objects, fear and suffering will be with you. Therefore Krishna told Arjuna to develop his discrimination and rid himself of body consciousness. Only then he would be able to develop integral vision.
For what can be known about God is plain to all, because God is plain to all, because God has shown it to them. Ever since creation of the world His invisible nature, namely His eternal power has been clearly perceived in the things that have been made.
