What is our life, but a tapestry of experiences, all stitched together by time?
Most people would give an arm and a leg (many sutures notwithstanding) to go back in time and relive their childhood.
But not everyone. There are some that would happily live in the today. But is that because they are mindful and spiritual? Or it is because they hate their childhood and are far better off today?
Then there are some that constantly live in the times to come. Neither happy with their childhood, nor happy with the way things are unfolding today. Ever writing in their minds, a chapter that has yet to be written.
As Vedanta teaches us, eveything around us is maya only. Yes we see life as a tapestry of experiences, but in reality, these are a string of lifetimes, of which we remember only a tiny part.
