Start with meditation, and things will go on growing in you - silence, serenity, blissfulness, sensitivity. And whatever comes out of meditation, try to bring it out in life. Share it, because everything shared grows fast. And when you have reached the point of death, you will know there is no death. You can say goodbye, there is no need for any tears of sadness - maybe tears of joy, but not of sadness. But you have to begin from being innocent.
It is said that time heals everything. Given enough time, things change, they evolve, get left behind and move forward. However, in pure, absolute unconditional love, nothing gets lost or forgotten. That love is never far behind, it is always there. Like an echo of what once was, and is no longer; and that is a void no amount of time can fill nor heal.
