All things in this world are based on Maya and is ever changing , never permanent, and we the humans are victims of it. No one can escape Maya or the will of fate....
Only an enlightened souls can realize this and live in this world without any attachments.
We poor mortals are incapable of such things and we often lament, bereave because of our heavy attachments to this materialistic world. No one is indispensable in this earth. We are all playthings in the hands of Kalapurusha....
Best wishes...
