North of London | The first thing we should do before getting into that discussion is determine what you mean by 'spiritual' since there are different understandings of what the word means and the understanding has changed through out the years.

When beliefs are shared by others, the idiosyncratic can become normalized. Therefore, recognition of social dynamics and the possibility of entire delusional subcultures is necessary in the assessment of group beliefs. Religious beliefs and delusions alike can arise from neurologic lesions and anomalous experiences, suggesting that at least some religious beliefs can be pathological. |
