Okay, I understand what you mean now. I was unaware of the word nirvana too, as I am not religious in the slightest.
You will be happy to know I first started meditating almost a decade ago. I have made great progress with my healing, but I am unsure if I will ever fully repair my brain. But, prolonged fasting certainly seems to be more effective to me than any other thing I have tried.
I am well aware of the powers of meditation. I have written before of how my deepest meditation sessions felt very similar to taking psychedelic drugs. I am not sure I agree with you on the cannabis, however. I believe the plant to exist for this very reason- to aide us on our journey within- as well as many other things.
