Question: That humming that I heard from you ... I want to know if it is a kind of meditation.Sri Chinmoy: Chanting is not, strictly speaking, a form of meditation. It is an invocation. You invoke God to enter into you, into your inmost self, into your inner existence. Meditation is different. While in chanting you usually invoke God to permeate your whole existence, in meditation you try, in a broader way, to enter into God's Infinity, Eternity and Immortality.
