Jai Baba Lal ji,
Past is dead but shadow past may follow the present for long,
Whatever it goes, imprints in mind for long, all incidents stored in mind at varying pitch with auto priority basis and recall the man with time and again for reference,
Man is not competent enough to erase the bad memory but can fill mind with some good thoughts,
And to make it favorable, man need to live in joy with, through eternal inherent love, it may overshadow the dark of ages,
Jai sri Sat Guru Baba Lal dayal ji,
