Meditation and Sudarshan Kriya, building strong relationships and having faith that a higher power is taking care of you, will help people come out of addiction.
Stop the struggle to strengthen the faith. Assume you have faith, if it shakes, pray to God to make it strong.
Life poses many situations when your faith is shaken. Inspite of being shaken if faith grows strong then you are on the right track!
Leaders should have foresight, intuition. They should have self confidence and should have faith in God.
