Although it has been renamed 'Wat Mongkol Jindaram', the locals still refer to it affectionately as 'Wat Rai Khing', named after the surrounding community that historically housed Chinese settlers who widely cultivated ginger. Wat Rai Khing belongs to the Mahanikaya sect of Buddhism, but there is no definitive evidence indicating the date of its establishment. According to local lore, the temple was founded in 1851. However, what draws many devotees is the revered statue of Luang Pho Wat Rai Khing, situated within the temple's assembly hall. Legend has it that the statue floated on the river and was brought to Wat Sala Poon. This image is a bronze statue in the Mara Vijaya posture, showcasing exquisite artistry from three distinct periods: the Chiang Saen style for its form, the Sukhothai style in its graceful hand position, and the enchanting face reminiscent of the Rattanakosin era. It rests upon a five-tiered base, believed to be crafted by artisans from the Lanna and Lan Chang regions. The assembly hall exhibits early Rattanakosin architectural style. Encircling the hall are four directional vihara, while a four-gabled hall stands at both the front and rear of the main building. Positioned within a pond, a pavilion houses a replica of the Buddha's footprint, located on the western side of the assembly hall. Luang Pho Wat Rai Khing, a Mara Vijaya Buddha statue, has a lap width of approximately 4.2 Thai cubits and a height of 4.16 Thai cubits, resting on a five-tiered base. The stately Buddha image sits facing north towards the river Nakhon Chai Si, also known as the Ta Chin River. According to the temple's history, Somdet Phutthacharn (Puk) invited the statue from Wat Sala Poon by floating it on a bamboo raft, known locally as a "phaa luk bua," which supported the statue during its journey. Upon arriving at Wat Rai Khing, the statue was ceremoniously enshrined on the full moon night of the fifth month, coinciding with Thai New Year or Songkran, drawing a large crowd. As the devotees lifted Luang Pho from the raft to the ceremonial platform, an astonishing phenomenon occurred: the bright sunshine suddenly vanished, giving way to dark, heavy clouds, tumultuous winds, and thunder, followed by a refreshing rainfall. This transformation brought a sense of joy and relief to all present as the people collectively prayed for peace and happiness, hoping "Luang Pho will bring calmness, dispel heat and suffering, just like the refreshing rain nourishing bounteous harvests." Consequently, this day, coinciding with Songkran, has been deemed significant, leading the temple to celebrate the annual festival of offering gold leaf to Luang Pho Wat Rai Khing, a tradition that continues to this day, passed down through generations in the form of oral storytelling, also known as "mukpath."
