The Self becomes stable as causeless peace and happiness when you stop imagining yourself to be a body mind object.
All worldly events, no matter how difficult they may be, aim to the revelation of your true nature as freedom, peace and happiness.
The mind may argue that without the me character, everything would be meaningless.
That is part of the illusion.
