Kripalu on Satsang:

  "Satsang is like a lake. You can bathe in it. By bathing in pure thoughts and good company, your thoughts and actions are then purified. In order to gain full advantage of Satsang, then you must learn the difference between right and wrong company. When one is convinced that God exists and is for real, then prayers get established and "shradda", or faith is created in Satsang. "Sat" means God. "Sanga" means friendship. Whatever helps you fall in love with God is called Satsang. "If you go around asking everyone where is God, you'll never find him. When people gather together to chant and pray - that is where you will find him."
