If we form our lives around the guru’s instructions, we will gradually come to hear the Lord in the heart and follow Him perfectly. Krishna states in Bg. 6.7 that “for one who has conquered the mind, the Supersoul is already reached, for he has attained tranquility. ” We conquer the mind not by whimsical activity but by engaging in the Lord’s service under our guru’s direction.
