From Draja Mickaharic's book on Spiritual Cleansing, this bath is used to sweeten one's life when one finds no mirth, no happiness, or is overly harsh on himself. One takes a cup of Parsley tea and mixes it with a tablespoon of honey, and adds this to their bath along with a prayer to see life be sweetened. One should stay in the bath 6 to 8 minutes and immerse (wet the head) at least 5 times.
This spell can be even better enhanced by combining it with other spiritual soaps and added oils like Uncrossing or Van Van, or by replacing the parsley with lemongrass. In fact, you can buy all the ingredients to start having a happier life right now through this link.
