Here is my current understanding of why we are here:
We are here to embrace with love the wounds of our past and the challenges of our present, seeing them as precious gifts which are constantly leading us to evolve into a higher level of consciousness. As we evolve into a higher level of consciousness, we are able to reflect more of who we truly are: spiritual beings who are here to love and be. Our egos, behaviors, emotions, and bodies are some of the tools that can help alert us to this grand truth.
One way to bring more consciousness to our lives is to become aware of the thoughts, memories, incidents, and interactions that trigger us, and then to get curious (without being judgmental) about the responses and reactions we have. The more we do this, the more we will come to realize that we do not have to be consumed and controlled by our egos, behaviors, emotions, and bodies – that we can allow our higher selves to become activated and to inform our human selves.
