Early accounts suggest that on the particular day that he was born there was a heavy thunderstorm and rain and was thus given the name of In Fuen, "quake" or Fahong, "thunder".

Previous biographies cite that as a child he would release the animals that his father caught for cooking or beg him to not hit fish as their heads would hurt.

Traditional accounts of his early career suggest Khruba Siwichai was an exemplary Buddhist monk, eating only one vegetarian meal a day and refraining from "habit-forming practices as chewing betel and fermented tea leaves, and smoking".

Khruba Siwichai had ordained monks and novices without been officially recognized as a "preceptor of the Thai hierarchy" leading to his confinement in a temple in Lamphun in about 1915-1916.

Apparently, two officials within the central Thai administration, the kromakarn which represented the Religious Affairs Department and the naaj amphur who worked on behalf of the Ministry of Interior, denied Siwichai's request to appoint the monks.

It is much more plausible that the secular officials may have denied approval of the monks that were to be ordained due to certain clauses in the 1913 Ordination act.

[16] Furious over Siwichai's insubordination, he was arrested by the police and brought to the Wat Lii Luang temple where the district prelate Phrakhru Maharatnkhon resided.

A committee was appointed by the provincial prelate and decided to forbid Siwichai to perform his duties as an ordainer and was demoted from his role as an abbot and subdistrict head.

The committee concluded ruled that the punishment of imprisonment for the ordination of monks should have come from Bangkok and that Siwichai's failure to attend the meetings were too severe.

Early accounts record that in the day of his cremation the sky became suddenly dark with heavy unexpected rain although it was not rainy season.

[24] Today, the Wat Ban Pang temple serves as a museum for the late Khruba, built by one of his original biographers Phra Anan Phutthathammo in June 1989.

The museum features collections of paraphernalia associated with his various construction projects including maps, a bench for resting, and a carrier bicycle.

For instance, the temple of Wat Phra Singha contains a shrine of Khruba Siwichai and features a long bronze statue of him, standing, in front of the "vihara".
