Description
The Pra Somdej Wat Rakang Kositaram Kru Wat Sadter amulets were found buried in the Putta Sayaas (Sayasana Reclining Buddha) statue, at Wat Sadter in Ayuttaya, and in the Chedi Stupa, which is recorded as having been built in the year 2414 BE, one year before the passing of Somdej Pra Puttajarn (Dto) Prohmrangsri (Wat Rakang Kositaram).
The Putta Sayaas reclining Buddha statue was built on the grounds of Wat Sadter from Bricks and Mortar with Cement sculpture in the form of a Buddha lying down on his side, with his head on his palm. The statue measures 52 Meters Long and 9 Meters Wide, with its highest point being 16 Meters High. The Buddha statue is hollow, and it was in the hollow chamber of the statue where the amulets were hidden.

Phra Somdet Kru Wat Satue were discovered in 1956 when Field Marshal P. Pibulsongkram The Prime Minister visited the Buddha image to cover it with gold leaf. At that time, the reclining Buddha image was in a dilapidated state, so he ordered the Municipal Public Works Department to renovate the reclining Buddha image thus finding the secret kru.
In those days Phra Somdej Wat Rakhang did not have the same popularityy as they do now and as such hardly made the news.

The amulets were made in remembrance of Somdej Dto’s Parents, as was the Sayasana Buddha statue and Chedi Stupa of Wat Sadter. The Pra Somdej Wat Sadter amulet is no longer in any serious need of doubt as to who made them when we study the History, Visual Aspects, and Documented Evidence, including confirmation by ex abbot of Wat Rakang Kositaram Luang Phu Nak, that the Pra Somdej Wat Rakang Kositaram found at Wat Sadter, were placed in the Buddha Statue and Chedi Stupa by Somdej Pra Puttajarn (Dto) Prohmrangsri himself, and are one and the same amulet with the Pra Somdej Wat Rakang Kositaram of Immortal Legend.
Actually the amulets from the kru of Satue temple are easier to see and are printed in a beautiful shape with clear definition andas such may prove to may be more popular than the amulets from the Kru of Wat Rakhang
The Pra Somdej Amulets of the Kru Wat Satue Hiding Place Find, were hidden in the Kru immersed below the water level for a very long time, which caused the original ‘Rak’ lacquer which covered many of them to wear out and detach from the surface of the amulets. This resulted in this series of Sacred Pra Somdej possessing their own inimitable appearance, which differs from the Pra Somdej Wat Rakang Kositaram, due to the long time period spent under different atmospheric conditions, with high moisture and humidity.
