Premanand Maharaj Ji
Why do I not get the full benefit of my charity and good deeds?
Boasting of good deeds weakens them
When people talk about their own charity and austerity, the effect of the deed fades. The sense of being the doer is ego, and it is removed through sadhana, satsang and grace.
They praise themselves with their own mouth. They describe their charity and austerity, and so its effect becomes weak.
