When I talk to audiences about the size and age of the cosmos, people often say, "It makes me feel so insignificant." I answer, "The bigger and more impersonal the universe is, the more meaningful you are, because this vast, impersonal place needs something significant to fill it up." We've abandoned the old belief that humanity is at the physical center of the universe but more come back to believing we are at the center of meaning.
I need to feel like the work I'm doing is not necessarily important, but meaningful, at least to me, because otherwise it just becomes a day job. It just becomes factory work and I get really frustrated.
The religion of the future will be a cosmic religion. It should transcend a personal God and avoid dogmas and theology. Covering both the natural and the spiritual, it should be based on a religious sense arising from the experience of all things, natural and spiritual, as a meaningful unity. Buddhism answers this description.
The animals of the world exist for their own reasons. They were not made for humans any more than black people were made for white, or women created for men.
For the rest of your life to be as meaningful as possible, engage in spiritual practice if you can. It is nothing more than acting out of concern for others. If you practice sincerely and with persistence, little by little, step by step you will gradually reorder your habits and attitudes so as to think less about your own narrow concerns and more about others' - and thereby find peace and happiness yourself.
