Atma shakti is the biggest protector or kavach during turmoil situation.
Atmashakti can only be developed by doing swadhyay.
Swadhyay will lead to tapasya, a proper and powerful way of life.
This will lead to ishvarapranidhana, which is getting absorbed in God.
For all this, gyan is needed.
Gyan is that vichara which connects us with our consciousness and with God, and brings transformation in our character.
Gyan will come through proper satsang which focuses on upliftment (uddhar) of oneself and is not limited to grammatical or textual jugglery.
Another thing which is also important is the blessing of God, which comes by prayer and healing sessions.
