Premanand Maharaj Ji
How do I deal with failure?
Prarabdha can make effort fail
Sometimes you try hard in the right direction and still fail because of prarabdha (past karma now bearing fruit). The lesson is that naam jap gives joy even in a failure that prarabdha brings.
If your prarabdha is bad, you may try a hundred thousand times and failure is all you will get. If it is good, a little effort brings success.
