I used to get deja vu on a daily basis as a kid. Eventually I stopped getting it at all and then I read how if you get headaches while meditating on the pineal gland or upper chakras it usually means the pineal gland is damaged.
So I started experimenting with vibrations in an attempt to develop a mantra that can directly empower the pineal gland.
Vibrating EEEEEEEEEEEEEEE into the pineal gland is by far the most successful. It takes a bit of practice to find the right part of your mouth and throat to use to adjust the pitch but it definitely works and is great for anyone who has a calcified or damaged pineal gland.
I still get dizzy and headaches after doing it but it is definitely empowering and I can hear it ringing into my astral hearing and head as well.
Try it and see for yourself.
HAIL SATAN!
