This question already has an answer here:
Whatever has happened has happened for the good. What is happening is also happening for the good. Whatever will happen will be for good also.
Reading the above translated text may be taken from Gita (I am not sure, but I gave reference link below) is quite understandable. But I want to know how did lord Krishna explain this "All for the good theory" which satisfy for each and every kind of individual?
Shall we consider it happened for the good if someone intentionally kills someoneone with out any reason?
Edit : reference
