The article dives into the legend of Heirang, a prominent monk associated with Haeinsa Temple, who lived in the Goryeo Dynasty over a millennium ago. In a time when the community was experiencing great discomfort due to mosquitoes, Heirang took it upon himself to gather all the mosquitoes and lead them to a remote area. This selfless act relieved the residents from worries of being bitten, contributing significantly to their summer comfort. However, it is said that this act came at a personal cost, as the mosquitoes took his blood, which is symbolized by a physical mark found on his seated statue.

Despite being a historical figure from the 10th century, Heirang’s legacy is well-documented, with records highlighting his relationship with King Wang Geon, the founder of Goryeo, showcasing Heirang's notable influence in both spiritual and political domains. Historical texts indicate their meeting and partnership during the establishment of the Goryeo kingdom, reinforcing the idea that Heirang played a pivotal role in guiding Wang Geon through these pivotal moments. Additionally, the praises from poets and scholars through the ages have solidified Heirang's reputation as a revered saint in Korean Buddhist history, emphasizing the virtues of sacrifice and selflessness in pursuit of communal well-being.

In contemporary times, Heirang's tales remain central to Buddhist teachings and are honored through monuments and memorials at Haeinsa Temple. A recent initiative has resurrected his likeness in a seated statue at the Inbeop Hall, creating a tangible continuation of his legacy for modern practitioners. As social dynamics evolve, the story of Heirang embodies the timeless values of compassion and dedication to the community, prompting reflection on the sacrifices made by those who serve others selflessly, even in the face of discomfort and adversity.
