The Lotus Sūtra declares in the 26th chapter on the “Mystic Phrases,” “I, the Heavenly King Vaiśravaṇa (Bishamon), will ensure that there will be no decline nor harm within the area of a hundred yojana, where this Lotus Sūtra prevails.”

The Nirvana Sūtra preaches, “You should know that the land in which this wondrous Sūtra on the Great Extinction (Nirvana Sūtra) is spread is a Pure Land as indestructible as a diamond. The people who reside here are also as indestructible as diamonds.”

The Sūtra of the Benevolent King states, “This sūtra with a thousand lights always shines within 1,000 Chinese li assuring that the seven calamities will not befall in that area.” The sūtra also preaches, “Many evil priests who wish to win fame and material gain will preach false teachings before such men in power as the king, crown prince and princes, eventually destroying the teaching of Buddhism, leading the country to ruin. Unable to distinguish right from wrong, the king will put his faith in their false teachings and promulgate arbitrary laws and institutions contrary to the Buddha’s commandments, ruining the teaching of Buddhism and destroying the country.”

As I contemplate these scriptural passages, it is preached in the Lotus Sūtra, “There will be no decline nor harm within the area of a hundred yojana;” in the Sūtra of the Benevolent King, “The seven calamities will not befall the area within 1,000 Chinese li;” and in the Nirvana Sūtra, “You should know that the land is as indestructible as a diamond, and the people residing there as indestructible as diamonds. ”
