The relationship between the Hebrew letters, vowels and intonations are explained in terms of their spiritual significance. The Zohar tells us that the letters, vowels and intonations are not merely the building blocks of language. They are the building blocks of the entire cosmos. They are the sounds of creation, the forces by which stars and planets are constructed, and by which physical and metaphysical worlds are erected. Just as a human voice in song can shatter glass and evoke tears, the Hebrew alphabet affects both physical and spiritual realities. We can set these forces in motion by meditatively scanning the very letters that speak of the secrets of the letters themselves. By so doing, we can draw spiritual sustenance and Light into our daily lives.
