how do i exercise my mind so i can see spirits and and be able to develop psychic powers?

Let go of everything that you think you know and pay attention to the world around you.

please dont. Demons are dangerous. Pray for salvation instead.

1) Find a proprietor of psychedelic mushrooms
2) Ingest said mushrooms
3) ???
4) Profit!

Smoke a lot of weed.

Lots and Lots of acid.

Meditating? if it doesn’t help, BANG your head to the wall.. 🙂

There are many hallucinogenic compounds that can bring this about. You may, in fact, be among that lucky few that can hallucinate all on your own.
I recommend, however, giving up now. There’s no conclusive evidence that these “mind exercises” actually do anything.

Drop a LOT of acid and shrooms.
Crazy person.

Go into a quite place and meditate.
