Shingon sect

The Shingon sect of Shinseism was founded in 234 at the tenth Great Convocation. A monk named Basso claimed to have discovered a lost teaching of Shinsei's, and his discovery served as the basis for the sect.

History
At the tenth Great Convocation, a monk named Basso came forward with what he called the "Diamond Sutra". The text appears to be mainly a reinterpretation of the Lotus Sutra. Basso claimed the Diamond Sutra was a "lost" teaching of Shinsei, though some believe Basso wrote it himself. Basso believed and taught the the Shinsei Sutra and the Tao of Shinsei were "elementary" teachings of Shinsei's, and placed all emphasis instead on the Diamond Sutra.

The leadership of the Brotherhood of Shinsei accepted Basso's followers as the Shingon sect, the first sect to be given official recognition and acceptance.

Teachings
Except for the members of the sect, few know what the sect actually teaches. Many believe Shingon to be an outgrowth of the unorthodox beliefs of the Dragon Clan, but even Dragon scholars do not seem to know th full extent of the sect's teachings. All that can be said for certain is that the sect teaches advanced meditation techniques designed to free the mind from all illusion.
