First the Hymn: Atharva Veda, Hymn 1.18
We drive away the Spotted Hag, Misfortune, and Malignity: All blessings to our children then! We chase Malignity away.
Let Savitar, Mitra, Varuna, and Aryaman drive away Stinginess from both the hands and feet: May Favour, granting us her bounties, drive her off. The Gods created Favour for our happiness.
Each fearful sign upon thy body, in thyself, each inauspicious mark seen in thy hair, thy face, all this we drive away and banish with our speech. May Savitar the God graciously further thee.
Antelope-foot, and Bullock-tooth, Cow-terrifier, Vapour-form, The Licker, and the Spotted Hag, all these we drive away from us.
How to change / alter it:
First of all the Gods that are called are Savitar, Mitra, Varuna and Aryaman, all sons of Aditi, all solar deities. Now for those serving the Universe, Savitar should be the Sun, Mitra and Varuna (keep the duet) should be Light and Darkness or Fire and Water, and Aryaman should be the Stars.
Now, although Varuna is a solar deity, and by himself is brilliant, together with Mitra, he adopts the more dark aspects, while Mitra adopts the brilliant ones. Together with Mitra they are the keepers of the Law and protectors of the World. When they are called together Mitra would symbolise, Day, Light, and Fire, while Varuna Night, Darkness and Waters (the heavenly ones).
Aryaman is more connected to the Milky Way, therefore in this incantation symbolises the Stars.
If you want to summon the Universal Powers, call them as that. If you want to change the pantheon, call the deities of your chosen pantheon according to their universal correspondence.
For the Greek Pantheon, you can choose one of these groups:
Helios for Savitar.
Apollo and Artemis for Mitra and Varuna.
Night or the Stars for Aryaman.
Apollo for Savitar
Castor and Pollux (correctly in Greeks pronounced Polydefkis – Πολυδεύκης) for Mitra and Varuna and
Artemis for the Aryaman.
Although the second group does not obviously correspond perfectly to the Universal aspects, it corresponds better to the nature of the Hindu Gods of the hymn.
The Favour is the Holly Grace of course.
Now, the symbols of misfortune are Antelope-foot, and Bullock-tooth, Cow-terrifier, Vapour-form, The Licker, and the Spotted Hag. Now, for Antelope-foot Greeks would use Κατσικοπόδαρη (Goat-Foot) while English would use Padfoot. The Bullock-tooth in Greek would be Στραβοδοντού (the one who has crooked teeth), but I don’t know of a similar symbol of misfortune in England. Vapour-form can be the Ghosts, Spotted Hag could be the Shtriga, the Licker can be the Succubus and Incubus. I don’t know what about the Cow-terrifier, but chose a forth symbol of misfortune.
Finally, the first verse says “All blessings to our children then!”. Now, the Veda usually express the maximum blessing as the blessing of our children for if the children are blessed, the parents should be blessed too. But, you can say “to our house” or “to our family”, or something alike, according to your needs.
If you want to empower the spell do it dayly for a week or three, by reading it three times each morning or each evening, while burning sandalwood and lavender.
I hope that Poseidon Alchemist and the Easy Witch will soon provide us with some more groups of divine beings according to pantheons they are more familiar with than me.
