When the vihara of Wat Saphan Sung was constructed around 2420 BE, a standard form of the Sorosamongkol Takrud was created on that occasion. It is known that these takrud were made in both lead and copper. The inner roll typically consists of five to six turns (some accounts mention seven turns). For this series, Ajarn Khong, a close disciple, inscribed the sacred characters on the metal sheets, while Luang Pu Iam himself performed the consecration. Donors who contributed one tamlueng received one takrud.
Later, during the construction of the chedi at Wat Saphan Sung in 2431 BE, it is said that the Sorosamongkol Takrud was created once again, exclusively for those who contributed to the chedi’s construction, with the donation amount also set at one tamlueng. On this occasion, takrud were likewise made in both lead and copper. There is information indicating that both Ajarn Khong and Luang Pu Klin (who was ordained in 2423 BE) jointly inscribed the sacred characters for this series. Although the chedi was not fully completed before Luang Pu Iam passed away in 2439 BE, Luang Pu Klin later oversaw its completion in the following year.
The yantras used in the creation of the Sorosamongkol Takrud consist of two principal yantras. The inner yantra is the Maha Sorosamongkol Yantra, while the outer yantra is the Tisarana-gaman Yantra. This form of takrud is intended for men. For women, the yantra prescribed is the Trini Singha Yantra, with a length of approximately seven centimeters, or in some cases a Sarika Takrud is given instead.
Because the creation of the Sorosamongkol Takrud was carried out with great care and required the chanting of the Maha Mun Mantra 10,000 times, it is said to have taken as long as seven years for its full potency to be realized. The power of this takrud is regarded as supreme, guarded by celestial beings, and capable of providing protection from danger both on land and in water. When kept within a household, it is said to protect the entire home. Its extraordinary potency is considered beyond the limits of complete description in words.
