When you join the Bhajan, sing in tune with the rest. Otherwise, your voice becomes harsh to the ear; it grates. So too, unless your life is in tune with the plan that the Lord has laid down, it spoils the melody, it is felt to be a disturbance. So follow the divine plan.
(From : Sai Veda, The Word of God, sayings of Bhagavan Sri Sathya Sai Baba)
