Somdej Buddhacharn Toh (B.E. 2331~2415), also commonly known as Acharn Toh or Somdej Toh, studied the Buddhist scriptures of the Pali Canon with several Buddhist masters. After becoming a well-known monk, he became the preceptor for Prince Mongkut, who later became King Rama IV.
During Rama IV's reign, Somdej Toh was given the ceremonial name Phra Buddhacharn Toh Phomarangsi. He was noted for the skill of his preaching and his use of Thai poetry to reflect the beauty of Buddhism, and most famous for making the Phra Somdej amulets.
Somdej Toh became an abbot of Wat Rakhang Kositaram and was promoted to the title of Somdej Phra Bhuddhacharn. Somdej Toh was highly intellectual and great in performing sermons. He is considered to be the most well known, respected, and beloved monk of the Thai people.
Somdej Toh left with us his lasting legacy and his blessings to the people of Thailand with the Phra Somdej that was blessed by him and the top Buddhist masters of his time. Somdej Toh would give a Phra Somdej to the Thai people every time he was invited to important events, to bless a new home, or during a simple lunch invitation. Before giving out one of his Somdej, Somdej Toh would give his blessings and tell the person accepting the Phra Somdej that this amulet would bless them with happiness and prosperity.
Somdej Toh is also famous for the Chinakmanjung Katha. The Phra Chinakmanjung Katha is an ancient Buddhist katha, inherited from Langka city, and was found in an ancient book by Somdej Toh. The Katha was improved and rewrote by Somdej Toh of Wat Rakhang.
The Phra Chinakmanjung Katha is very powerful katha and believed to be the supreme Buddhist spell because the words of this katha invite the magic power of Lord Buddha Somdej Phra Sammasambuddhachao, other Lord Buddhas and Phra Arahuntaras (supreme monks who're nearly enlightened ) to protect the worshipper from their heads to their toes in addition to dispelling all evils.
Somdej Toh had also been mentioned in the story of Nang Nak, commonly known as Mae Nak to the Thais. As Nang Nak was furious in the villagers whom exposed her death news to her husband and making revenge against them, it was Somdej Toh whom in the end came to the villagers' rescue, and had managed to persuade Nang Nak to put down her grievances. It was believed that Somdej Toh had removed Nang Nak's forehead skull and had kept it with him since, though after Somdej Toh passed away, the whereabouts of the skull remained a mystery.
Somdej Toh passed away in B.E. 2415 at the age of 85, and believed to had passed away at the foot of the on-going construction of the big standing Buddha statue, known as LP Toh, in Wat Intrawihan.
