The things that are happening in your life are not random events. They are the immutable unfolding of the karma of the lifestream which you have selected. You selected this lifestream because these were the experiences that you needed in order to grow spiritually.
Our True Self, the chitta, is the awareness within, the awareness that existed before this body was formed and which will continue to exist after this body perishes. Our True Self is a tendril of awareness from the Universal Consciousness, present in this body to experience the maya (illusion) of the material world.
This awareness has probably been around for a very long time and has experienced incarnations in multiple physical bodies. Each incarnation is for the purpose of learning how to cope with the challenges of the maya. The purpose of incarnation is to learn to resist the lure of the material world. When the chitta has learned to disentangle from the maya, it will no longer be drawn to this world. Then it will no longer need to incarnate and will be liberated from this cycle of birth and death.
