Besides, for a student it is most advisable that he must keep his conversation limited so as not to say things which might seem to the others too occult, too mystical, too spiritual. Our conversation must be like an ordinary conversation. Things about spirits and ghosts and elementals, apparitions and all sorts of things -- people like to talk about their past and present and next incarnation, what they were and what they will be. We must not commit ourselves in talking about these things. These things are for every individual to find out for himself. By talking we neither do good to ourselves nor good to the others.
