He may become so sensitive as a consequence of meditation that other people's thoughts, feelings, or passions may reflect themselves into his own nature temporarily when he is physically near them or mentally dealing with them. In such cases he will probably mistake the result for his own, thus expressing what is really alien to his mind or acting outside of his individual pattern of life.

Unwittingly, he may become disloyal to the Ideal merely through being ignorant of what is happening psychically, and unguarded against it.
