A visitor from the West – a Professor – just returned from a visit to Satya Sai Baba’s place, took to Mother a bead which the Baba had ‘created’ and given him. He gave it to Mother and asked about the nature of the bead. She felt it with her palms and said it was a materialised object. Then he asked what she thought of the Baba. Mother told him : One Guru does not pronounce upon another.
