Shemhamphorash. 72 Angels

The Magick of the Shemhamphorash, sometimes called the 72 Angels of the Divided Name or sometimes called the 72 Angels of the Explicit Name of God. App includes a traditional Psalm (different traditions use different Psalms, the app's Psalms come from 6th & 7th Book of Moses), the traditional & modern magickal uses of the angelic name and seal, the spirit's name in Hebrew letters and the angel's personal seal. You can use these angelic seals for magick, meditation, invocation, evocation, or something of your own design. You could add them to petitions, talismans, etc. The FAQ includes tips/observations on how to use the angels for magick or meditation, but it is not a full introduction to the the 72 Angels of the Shemhamphorash. It is a pocket reference.
These angels are the same as the Shem HaMephorash, as you likely know there are a lot of different spellings for names in Grimoires because Hebrew did not actively use vowels, because of mistranslation from Hebrew to Latin to whatever modern language you speak). It can be frustrating, but less than a few hundred years ago, having this information could get you killed. In Europe and in the Americas. In 1692 they had the well-known witch panic in Salem. So, misspellings are common in our area of interest from bad scholarship and also fear of being too knowledgeable.
Finally, for legal reasons I will say that this app is for entertainment. If the angel magick is supposed to heal a condition, it might heal it, but it might not. You should seek medical advice from a licensed doctor. Angel magick should be used to compliment a "real world" physicians advice. Angel magick should never be used to replace medical advice. Spiritual healing is a complimentary treatment, not a replacement.
