Enjoy each day of your life to the fullest. We are born, we have a lifespan of 0 to 100+ years.. we die, we become food for the trees, creatures, plants and birds of future generations. That is the life cycle. It is our hiding from these facts that creates suffering in our lives.
This is the same life cycle for all living things. Anything that is “alive” feeds on some other alive “thing”, or its dead body. This is nature, and the further we get from living this way, the more suffering we experience.
Anything added to this is fairytales and causes suffering.
