Old concept. Old overused phrase, maybe. But I do ponder on this one all the time, momentarily, both puns intended.
We can only be here now. We are only here now. We exist instantaneously at all times, literally. Yet, the past and the future haunt us. We spend our lives striving to be something we are not, to have something we have not, to understand something we do not, to conceive of purpose we do not have. Everybody, yeah everybody.
We are cursed by the vanity of humanity and the pain and suffering of self awareness and self pity.
Only the enlightened will realize the truth, we are in this moment for good.
