20,000,000 Buddhists murdered by the Muslims during the Middle Ages

Nichiren comments on  the Indian cataclysm of the death of twenty million Buddhists and the near extinction of Buddhism at the hands of the Muslims.

"When the spirit of Buddhism is lost or hidden away, people will all let their body hair and nails grow long. Worldly ethics and laws will be forgotten and ignored. Loud noises will come from the sky and the world will shake and move, as though it was on a spinning waterwheel. The walls of the cities, houses and dwellings, will collapse. The medicinal properties of plants will vanish. All but the highest five regions in the world of form and desire, will no longer possess the seven flavors of the tongue or the three good powers of the earth: worldly law, natural law and the Buddhist law. Eventually everything will die. All the positive teachings that lead to freedom will disappear. Flowers and fruits will hardly grow and all become sour. Waterwells, springs and ponds will turn to dust and the earth will buckle and open into dark and ugly rifts. Mountains will burn. The rain dragon will not bring rain so the crops will wither and die. All life will disappear; even grass will not grow. Even the sun and moon will no longer shed their light!"
