Watch this video for a very deep exploration of what is chardi kala:
"Chardi kala is not being in a negative situation and saying, 'I will think positive'. Chardi kala is 'What can the world do to me, I'm not even here.' When the world can't even touch you, that's a completely different chardi kala."
"Somebody who is already dead, what can you take way from them? You take their possessions away, they don't mind. You take their life away, they don't mind. You can't do anything to them."
