It always amazes me when I learn something new that is so obvious that I missed it for years. The past is beyond change because in reality it only exists in memory.We can talk about it ,watch videos that conjure stories and memories but it only exists conceptually. The same is true of the future. We can look forward to it, plan for certain goals and dream about outcomes, but it also is merely conceptual. What does exist in the concrete is the” now”. The present moment is more that a memory or a dream, it is real and the one path where our actions are somewhat under our control. Today is more than a memory or a wish,it is the time when life occurs and change and meaning are more than concepts.
