To produce spiritual states of mind, would there be certain neuroanatomical objectives or goals for invoking them? If you control your mind, your motor faculties, your cognitive patterns, aren't you influencing electrical and energetic flows within your body, spine and brain? So, if you understand your brain as a computer with complex, biological transistors, then changing the electrical and energetic flows, globally, regionally and circuituitously absolutely has an effect on how they regulate themselves. Further, this is a discussion of neuroanatomy as it relates to spirituality in general, with a strong focus on Buddhist meditation. Christianity and other religious traditions have practices which can evoke similar and potentially identical spiritual states of mind. Some kinds of prayer, especially when extended, force you to open your heart and surrender yourself and your mind to God.
How does one become familiar with different systems of knowledge and culture perpetuation? Like Merlin and the druids of Celt, one accrues this knowledge over time, by learning to weave ideas and their semiotic pointers.
