For the first part of the bath, you can either run a tub of warm water, or just turn on the shower.
Disrobe while reciting the following Psalms: 14 or 53, 27, 54 or 69, 81, 105
Then recite this exorcism over the tub of water. (Or if you use the shower, place your hand on the shower head while you exorcise.)
“I exorcise thee, O creature of Water, by him who hath created thee and gathered thee together into one place so that the dry land appeared, that thou uncover all the deceits of the enemy, and that thou cast out from thee all the impurities and uncleannesses of the spirits of the World of Phantasm, so they may harm me not, through the virtue of God almighty who liveth and reigneth unto the ages of the ages. Amen.”
Finally enter the bath and wash yourself while intoning the following names two or three times:
“MERTALIA, MUSALIA, DOPHALIA, ONEMALIA, ZITANSEIA, GOLDAPHAIRA, DEDULSAIRA, GHEVIALAIRA, GHEMINAIRA, GEGROPHEIRA, CEDAHI, GILTHAR, GODIEB, EZOIIL, MUSIL, GRASSIL, TAMEN, PUERI, GODU, HUZNOTH, ASTACHOTH, TZABAOTH, ADONAI, AGLA, ON, EL, TETRAGRAMMATON, SHEMA, ARESION, ANAPHAXETON, SEGILATON, PRIMEUMATON”
When you are perfectly clean, exit the bath (draining the water if necessary) and use the Water Sprinkler to splash yourself with Holy Water. (If you don’t have the sprinkler, then use your fingers.) While you do this, say:
“Purge me, O Lord, with hyssop, and I shall be clean; wash me, and I shall be whiter than snow.”
Now you get dressed – but you’ll be disrobing again soon enough. Therefore, I just throw on a robe or towel at this point. Then repeat these Psalms: 102, 51, 4, 30, 119:91, 114, 126 and 139
Finally we’ve reached the second part of the bath- which is really a kind of baptism. Fill the tub again with warm water. If you only have a shower, then fill a pot with hot water and set it in the shower stall. Then recite the following prayer over the water:
“EL strong and wonderful, I bless thee, I adore thee, I glorify thee, I invoke thee, I render thee thanks from this bath, so that this water may be able to cast from me all impurity and concupiscence of heart, through thee, O holy Adonai; and may I accomplish all things through thee who livest and reignest unto the ages of the ages. Amen.”
Then recite the following exorcism/benediction over the salt:
“The blessing of the Father Almighty be upon this creature of salt, and let all malignity and hindrance be cast forth hencefrom, and let all good enter herein, for without thee man cannot live, wherefore I bless thee and invoke thee, that thou mayest aid me.”
Finally, recite Psalm 103 over the salt.
Cast the salt into the water. (Some manuscripts of the Key say to cast in consecrated spices as well, but none of them mention which herbs. If you wish to use herbs here, I would suggest the nine herbs used in the Water Sprinkler. You can brew them up just as for a Hoodoo bath, and pour the resulting “tea” into the water with the salt.)
Now disrobe once more while intoning these names:
“IMANEL, ARNAMON, IMATO, MEMEON, RECTACON, MUOBOII, PALTELLON, DECAION, YAMENTON, YARON, TATONON, VAPHORON, GARDON, EXISTON, ZAGVERON, MOMERTON, ZARMESITON, TILEION, TIXMION”
Enter the bath once again, recite Psalms 104 and 81 and pour the water over your head several times.
Once done, exit the bath and dry off with a white towel and put on clean white garments.
I also have another bath that follows a more Hoodoo-style pattern, which I give to anyone who comes to me for magickal help (uncrossing, etc). I’ll post that one here later.
