"We learned from the divine, prophetic, and religious Kabbalah that when the wise mystic performs the Tzerufim (Permutations), the Ruach haKodesh (Holy Spirit) rests upon him. At first, the things he obtains from the Tzeruf will fill him with fear and awe; his hair will stand on end, and his organs will tremble. Then, if he is worthy, Ruach Elohim (Spirit of God) will rest upon him. He will feel as if his entire body from head to toe, were anointed with anointing oil. He will become the anointed of haShem (the Name), and become his emissary; he will be called the Malakh haElohim (Angel of God) and his name will be the name of his Rav (Master), which is Shaddai (Almighty), who is called Metatron, the Prince of the Presence (Sar haPanim)."
