Satsang is the boat to cross the Maya or worldly ocean. If we sing a bhajan of Mahaprabhuji or other saints, they become the captain of our satsang. Their energy comes to us in their subtle or energy body even if the great saints have left ages before. As soon as we remember them, their energy is there. When we remember the Divine, this energy comes and takes place in our consciousness, our imagination, our intuition, our feelings and intellect.
