Is it from The Mother or someone else?

Q: How to recognise that a particular thought, feeling or impulse to action has come from the Mother herself and not from some universal force? If it is apparently of falsehood it can be recognised as such, but there are many others of a different character and sometimes one goes on thinking that they are prompted by the Mother from within even though they are not.

A: It can only be done by discrimination, care, sincerity, a constant control with regard to the mind’s movements and the growth of a certain kind of psychic tact which detects any mental imitation or false suggestion of its being the Mother’s.
