This translation of the elemental prayers is the same that is used in the Golden Dawn rituals and most likely was translated by S.L. "MacGregor" Mathers. An alternate version can be found in Waites's version of Dogme et Rituel. It appears, that in part, these may predate Levi, and may be found in the likes of Comte de Gabalis as well as the Grimoirium Verum, both most likely dating to around the end of the 17th century.

PRAYER OF THE UNDINES (WATER SPIRITS)
Dread King of the Sea, who hast the Keys of the floodgates of Heaven and who enclosest the subterranean Waters in the cavernous hollows of Earth; King of the Deluge and of the Rains of Spring; Thou who openest the sources of Rivers and of Fountains; Thou who commandest moisture, which is like the blood of the earth, to become the sap of plants: We adore thee and we invoke thee! Speak thou unto us Thy inconstant and changeful creatures in the great Tempests of the Sea, and we shall tremble before Thee. Speak unto us also in the murmur of limpid waters, and we shall desire thy love. O Vastness wherein all the Rivers of Being seek to lose themselves, which renew themselves ever in thee. O Ocean of infinite perfections! O Height which reflectest Thyself in the Depth! O Depth which exhalest thyself into the Height! Lead us into Immortality through sacrifice, that we may be found worthy one day to offer unto Thee the Water, the Blood, and the Tears, for the remission of Sins! Amen.
