Birth and death pertain only to the body, they are superimposed upon the Self, giving rise to the delusion that birth and death relate to the Self. The universe exists within the Self. Discover the undying Self and be immortal and happy. Be yourself and nothing more. Thoughts change but not you.
There is neither past nor future; there is only the present. Yesterday was the present when you experienced it; tomorrow will also be the present when you experience it, therefore, experience takes place only in the present, and even the present is mere imagination, for the sense of time is purely mental.
All that is required to realize the Self is to be still. What can be easier than that? Your true nature is that of infinite spirit. ~ Ramana Maharshi
