Premanand Maharaj Ji
What should I do when I start feeling I am a good and virtuous person?
Fear the pride of virtue
Thinking of yourself as virtuous is a fall for a seeker. Call out to Bhagwan the moment it arises and ask to be saved from ego.
Wherever the feeling of your own virtue arises, cry out Radha Radha Radha, Krishna Krishna Krishna, 'Lord, save me, ego is coming.'
