When you move on in life, you always leave behind some things- some myths and some mysteries, that cannot be fathomed by the heart, without going back to the past and visiting yourself again; in that time, at that place. You can only understand such things and solve such riddles if, in your imagination, you can live the life again and be in that place again, where you left a part of you.
We live in the present all the time and the past does not matter anymore. Only if we can understand this in the past, when the past is the present, we would be able to live every moment with satisfaction and joy. Only if we understand that the quarrels and miseries, the sadness and even the strongest of problems of the present will not matter to us in the future in a way they do now; we can be content with whatever our present holds in store for us.
