Q: I recently had what I would call an experience of ‘dissociation’, accompanied by a profound sense of anxiety.  This has not happened before and maybe it was ‘psychotic’ rather than anything else. But research suggested that such an experience may follow prolonged periods of unsupervised self-enquiry. Can you tell me how to avoid a recurrence?  

(I have been following the teachings of Nisargadatta for the last 3 years of a 10-year period of self-enquiry meditation. I see in the Q&A postings that having no access to a teacher is a common theme and makes progress monitoring and understanding of book-based teachings difficult).
