The story tells of one occasion, while dwelling in Nikhotharam monastery in Kappiravatthu, the Buddhas delivered a sermon to the monks. The Buddha mentioned one of his previous lives and told this story. Once upon a time, there was a poor couple who lived in Vannampakham village in Champa Nakhon kingdom. When their first son was born, the solar eclipse happened. Therefore, they gave a name to their son as Suriyakhat (solar eclipse). Later their second son was born. At the time, the lunar eclipse occurred. So, they gave a name to their second son as Chanthakhat (lunar eclipse).
