Focusing on the holiness of the text, Jewish mystics consider every nuance of the text to be a clue in discovering divine secrets, from the entire text to the accents on each letter. Once one can find such knowledge, one can use the text in mystical rituals to affect both the upper worlds (heavens) and the lower world (our world). The name of God is considered one of the greatest sources of power and is assumed to be hidden in various forms throughout the text. Much activity involves rearranging the breaks between words to seek out different names for God as well as other aspects of hidden knowledge.
