Who has had experience with an entity that has destroyed your life (or tried) or caused harm to you? How did this start? Im not worried much about this I try to be as respectful as I can. Has this ever happened after ritual evocation/invocation?
The only entities that have tried to ruin my life per se have been parasites.
However it also depends what your definition or ruin is.
Just impacted your life in a very negative way. I hear/ have heard if youre not careful working with entities they can cause harm.
I know some do put you through hard times to make you stronger.
It has mainly to do with fear due dogma. Strong character and respect for the entity. Say you try evocation, it doesn’t work, don’t blame that entity but work on your skills.
Banish if you feel to.
