Swami Mukundananda
How can I stop feeling proud that I am the doer?
Practice humble thoughts
Humble thoughts are the reverse of the pride of being the doer. Repeatedly practice the sentiment that Shri Krishna is the source of power and the enjoyer of the fruits.
Oh Shri Krishna, whatever I did, I did not do it. You enabled me to do it, because You are the source of the power, and the enjoyer of the fruits of this work is also You.
