Zohar

"There are halls in the heavens above that open but to the voice of song."

"When men in prayer declare the Unity of the Holy Name in love and reverence, the walls of earth's darkness are cleft in twain, and the Face of the Heavenly King is revealed, lighting up the universe."

"A man should so live that at the close of every day he can repeat: "I have not wasted my day"."
