Once I met a great scientist in New York, who said to me, touching his pen lying on the table, "If there is really a spiritual power, a mystic power, I would like to know if it is possible to lift this pen by this power." I said, "Do you really think that a mystic will waste his energy in making this experiment, raising a pen in space? And if he did it, what would he have gained? Would he not sooner raise a soul higher, bringing him to another sphere, raising his ideals, his aspirations, instead of trying to raise this little pen lying on the table? What will he get for it? Praise? He does not want it. That people will believe in him? He does not care. Praise is not his object nor does he care if people believe in him. Why should he trouble about these things?'
