I seen heaven once. I peered into heaven the first time I took MDMA, it really is up in the sky (appears to be just above the clouds)
I didn't see god there, it was just a feeling of unconditional love, benevolence, bliss. Yes, I was on MDMA, but that doesn't mean to me that plane of existence doesn't exist. I just feel as though... I don't belong there, it isn't for me, I don't accept the notion of forgiveness, ect.
To all you true Christians out there.. all the power to ya though, if that's your thing.
