Protection against Asuric attacks and influences

Q: How should one protect oneself against the attacks and influence of the Asuras?

Through purity and sincerity one is secure from the Asuras. They might give you blows, they might deceive and befog the mind, they might retard and make you commit mistakes, but if you have the white light of purity and sincerity they cannot harm you. There is no definitive fall, you will go through.

– Sri Aurobindo
