Worship of the Divine must stem from the heart. When devotion flows from the heart, the Voice of the Divine can be experienced in silence - Sabda Brahman (sound of the Supreme Spirit). This was the experience of Ramakrishna Paramahamsa. He observed perfect silence awaiting the Voice of God at any moment. Can the Divine voice be heard in the cacophony of daily sounds? No. Devotees must practice reticence. When speech is restrained, the voice of the Spirit within makes itself heard. That is subtler than the human breath. It is only through Prapatti or total surrender, that the Divine can be experienced. It is an experience that can be had every moment of your life. (SSS Vol.25)
