Steve Harris posted in the face of great philosophizing:

There was once a humble and deeply religious peasant. All day and night
he recited mantras. After time he began to demonstrate miracles. (Footprints
in rocks, rainbows, etc, The usual Tibetan miracles.) A renowned scholar
came and asked, "What is your practice?" The peasant replied, "I just
recite OM MANI PEME OX." The scholar was aghast, "This is completely wrong!
You must recite the mantra correctly, OM MANI PEME HUNG!" The peasant, being
very humble, agreed and chanted the mantra correctly. From then on, there
were no more signs of miracles.
