Incantations are magick word spells they are used  for many things i will write 5  that i found huge success with our dear @Anewbiz  can test them himself . To be chanted repeatedly not like mantras you chant them loudly focusing on the goal put your energy your soul on it. 

Poems are offerings to a spirit let it know you will offer it one and write that it will be pleased and you can use it in summoning 

 

Angelic banishing this is used for clearing the space you visualize strong astral weaves coming out of you while chanting them to be spoken loudly with authority and a sure knowledge that they will work it helps raising your hand pointing it at the space its for negativity and dismising an entity however if it is a strong one it will come back so i suggest you do the lesser banishing or call a god to dissmiss it

chant it 3×
