This brings us to the question of mediumship. Sometimes people may sing songs which do not belong to them, which they have never learned, which they are not supposed to know. There was a young girl in Bombay who never knew Persian, but there used to be times when she would speak Persian; and the Persian was so good that learned Persian scholars used to come and discuss with her. She used to discuss points of metaphysics and would always stand firm in her arguments; and they were deeply impressed by it. And then at other times she did not know Persian.
