Hi i am asking about how many days or months i have to practice the LBRP before i move forward to any other rituals like supreme banishing ritual? And how i can make sure i am ready to move for the others rituals specifically in golden dawn path? Thanks!.
Well to start, you should get familiar with the golden dawn material, they give a clear outline of the work required and the information you should learn to help you work with the rituals, meditations, pathworkings, godforms and so on.
Many people seem to confuse the elemental grade work and think its just about doing a ritual. there are meditations and other practices that go along with the system. Its about helping to bring balance to yourself, and in doing so, to know thyself. this will lay a foundation for future work.
How long that takes depends on you and your mental state at the start of the work, are you following the structure GD layouts or skipping around or taking bits from various videos etc.
The LRP formula is a tool, Banishing and Invoking are variations of the formulic structure of the ritual. They serve a purpose and you'll come across various sources that preach using one over the other, a healthy practice will use a combination of them to aid you in your work.
Nick Farrell and some others will advocate for using the LIRP more for the grade work, other sources Regardie, Christopher (LTC) will say to use the LBRP more to keep your ego in check.
