The universe is in constant flux and transformation. A moment by moment displacement and reformation.
The universe is everything which is known and experienced, and much more. Even the most knowledgeable among humanity regarding the happenings of our ever expanding universe are merely as a child on the beach looking across the ocean as far as one’s vision might allow. If we only knew what we don’t know, perhaps our ignorance would overwhelm our confidence.
Our concept of reality is limited in scope and to certain specifics. What we know amounts to perceptions as defined by our instincts and our experiences. Our instincts are innate, our experiences are an expanded context of the function of those instincts within the framework of the natural principles of the universe.
Our lives are a moment by moment quest for comfort. An instinctive effort from birth to death. The specifics as to how we achieve that ever elusive goal are limited to the framework of certain seemingly consistent principles within the context of the physical universe.
Our natural instinctive aversion to discomfort is complemented by a secondary instinctive sensitivity for the suffering of others. In fact, we become distressed and therefore internally uncomfortable at the mere sound of the suffering of any other sentient being.
Our instinctive aversion to suffering then seems to not only serve as a means of self preservation, but likewise as a basis for social interaction. Such seems to be the most fundamental principle of our very being as sentient beings within the the context of the constant flux and transformation of our niche of the known universe.
