Lol but what will you use the Power though?
I went for BoL first since it transforms you inside out to your original perfect DNA,
where as power will make you a strong manifester/ Jedi like doing years of Chi kong for years.
This could be dangerous if someone isnt purified inside out as you will be manifesting things quickly even negative thoughts if you are not careful and dwell in them.
If you are already practicing energy work like astral projection, healing etc then Power would make those skills amplified dramatically.
But just like Master Franz Bardon teaches…equalibirum of mind soul and body must be mastered first.
