Incantations for harnessing different kinds of väki. If many of them sounds similar, it's because many come from the same North Ostrobothnian tietäjä, Jaakko Tolvander.
To harness the väki of thunder, you typically need to collect dirt during a thunderstorm, or a shive from a tree struck by lightning. Little stones from the edge of a puddle formed on a rock during a thunderstorm is also ok. While doing this, chant the incantation.
 Oi ukko ylijumala Vaari vanha taivahainen Lähe kansani kylähän Puolestani puhumahan Vierestäni virkkamahan! Minä mies vähäväkinen Uros heikko hengellinen SKVR XII1 3715 | Oh ukko, high god Old celestial grandfather Come with me to the village/for a visit To speak on my behalf To state next to me! I am a man of little power A male with weak spirit |
To harness the väki of a forge, you go into the forge before sunrise, push the bellows nine times, take ashes into a white cloth thrice with the blade of a knife, and chant:
Liekkö miestä lietsehellä Alla ahjojen apua Miehen ainoan avuksi Yksinäisen ympärille Vasten muita vastuksia Vasten vastuksen väkeä Tämän auringon ijäksi Miehen poijan polvueksi? SKVR XII1 3705 | Could there be a man at the blower Help beneath the forge To be the only help of a man Around a lonely one Against other opponents Against the väki of the opponent For the age of this Sun For the generation of a man's son? |
Then, three drops of blood from the ring finger of the left hand is shed into the forge. The last two lines emphasize this väki is being harnessed for eternity. Close the rag with a red thread and carry it in your left armpit.
To harness the väki of fire, take ash from three roots of a tree that was burned in a forest fire with the blade of a knife and put it in a white rag and chant:
Onko poikaa panulla Mielismiestä tulosella Miehen ainoan avuksi Yksinäisen ympärille Vasten muita vastuksia Vasten vastuksen väkeä Tämän auringon ajaksi Miehen poijan polvueksi? SKVR XII1 3711 | Is there a son by panu (fire) A favourable man by the fire To be the only help of a man Around a lonely one Against other opponents Against the väki of the opponent For the age of this Sun For the generation of a man's son? |
Then, three drops of blood from the ring finger of the left hand is shed onto each root. Close the rag with a red thread and carry it in your left armpit. The väki of fire manifests as lightning around this before an event.
To harness the väki of rock/stone, take water from a pond on rock which has no rivers, put in blood from three forest animals as well as your own left hand ring finger, make a fire on the rock and make the water boil, pour some o the water on the rock three times and then take some of that boiling foam and ash and chant:
Liekkö vuoressa miestä Liekkö poikoa pohjasella Alla kallion apua Kihlahuivin kiiltäväistä Vaskivöisin välkkäväistä? Anna nyt ukko unkertasi Miesväki voimovasi Alta kallion apuva Voimaksi vähäväkisen! SKVR XII1 3634 SKVR XII1 3632 | Could there be a man in the mountain Could there be a son in the north Help beneath the rock A shining engagement scarf A sparkling copper belt? Give now, man, your [?] Men, your power Help from beneath the rock To be the power of the weak! |
Or alternatively just strike a rock thrice and chant.
To harness the väki of a tar pit, go to a tar pit the creator which is unknown. Put three pieces of wood to smoulder there, go around the pit thrice while not covering your head, and put in three drops of blood from your left hand ring finger. Chant:
En sinua kullin kutsu Hopealla houkuttele Kutsun kullan kantajalla Hopean vajehtajalla Katehia kaatamahan Vastuksia voittamahan | I do not summon you with gold Tempt you with silver I summon with the carrier of gold The [?] of silver To topple kades To defeat opponents |
Then take ash from the pit thrice with the blade of a knife.
Tuli kokko metsän äijä Metsän kaarron kaunis vaimo Nosta poikasi porosta Tyttäresi typenestä Miehen ainoan avuksi Yksinäisen ympärille SKVR XII1 3709 | Kokko/bonfire, lord of the forest came The beautiful woman of the forest arch Rise your son from the ashes Your daughter from the embers To be the only help of a man Around a lonely one |
And a small flame you see comes with you. Then you can go to graveyards with no worry and do all kinds of other sick stuff. [The runosinger's words, not mine!]
