What is your preferred method of banishing besides LBRP?

[Borgy]

You are powerful yourself too and then a simple banishing like this can be enough:

Am I wasting lucifers time?

A tip for you both. Use a Sigil and ask in the beginning of your invocation. ‘I only invite the spirits I work with, other entities with negative intentions are not welcome’. After the invocation ‘I ask entities with negative intentions other then the spirit I work with, to depart’ This is simple banishing and will prevent parasites.

I do advise the LBPR for grounding, healing and banishing once in a while.
