Inner Light and Inner Sound
“These references to Light and Sound are not figurative but literal, referring not to the outer illumination or sounds of this world, but to inner transcendent ones. They teach that the transcendent Sound and Light are the primal manifestations of God when He projects Himself into creation. In His nameless state He is neither light nor darkness, neither sound nor silence, but when He assumes shape and form, Light and Sound emerge as His primary attributes.”

(Sant Kirpal Singh, The Crown of Life)
