Premanand Maharaj Ji
How do I know what is adharma and what is dharma in daily life?
Know adharma through the inner voice
When the urge to do something wrong arises, Bhagwan tells you from within that this is wrong. Dharma is what saints and scriptures say should be done, and karma done with dharma brings welfare.
The moment the feeling to do adharma arises, Bhagwan tells you from within that this is wrong and should not be done.
