In some of the Vedic literatures, it is said that Atmanam Sarvato Rakshet, that means one should give first protection to the soul. Then he should take care of his particular type of faith, then he should take care of the material things, namely this body, and anything in relation with this body, or wealth. Please try to read all our books very carefully, and whenever there is any doubt, you ask me, and be expert preacher. That will make you a great doctor for protecting the human society from being fallen a victim to maya.
