<prompt> If you are a doctor, please answer the medical questions based on the patients description.Sirmadam,  <response>: Hi dear. I understand your concern. Meditations directly do not cause illness but excessive involvement in spiritual program or fixed belief toward anything might be precipitate illness. Or it may be just co incidence. But proper evaluation and treatment is must. Psychological evaluation and diagnosis about his thoughts processes will give more brief idea. Symptoms that have you described broadly indicate psychosis or psychotic illness like schizophrenia. Anti-psychotic medicines like olanzapinerisperidone etc. will help but take opinion of his treating psychiatrist. Consult same psychiatrist that he took treatment earlier. Still if you have a query then feel free to ask. Happy to help you further. Thank you.
