Kruba Srivichai (B.E.2421~2481) was ordained as novice monk under Kruba Kadtiya and he learnt everything under his teacher. One day, one villager gave some meat to Kruba Srivichai. After he consumed, he vomitted and fell ill. Since then, everytime he consumed meat, he would vomits and falls ill. Hence, Kruba Srivichai became a vegatarian and stopped eating meat. At B.E.2427, Kruba Srivichai helped Kruba Kadtiya to build a temple at Ban Pang. When Kruba Kadtiya passed away, Kruba Srivichai became the abbot of the temple.
Kruba Srivichai observed a very disciplined rountine daily. He woke up at 5am to sweep the temple's compound, then he would performs chanting and after which, he would go for alms in the village. In the afternoon, he would teaches the villagers, novice monks and children on Buddha's teachings. In the evening, he would performs chanting again and practice Sammadhi. He stayed in the temple and hardly left the temple.
Kruba Srivichai became very thin because he stopped consuming meat. The villagers seeing that, respected him and offered him many expensive gifts but Kruba Srivichai just passed the gifts to the poorer villagers. He was contented with a meal of small lump of rice with little vegetables each day.
Kruba Srivichai has been called the 'Engineer Monk' because he mounted and supervised over one hundred construction projects in northern Thailand, including many temples. He had organized the building of a road leading to Wat Prathat Doi Suthep, the grandiose temple complex that sits on a mountain top overlooking the city of Chiang Mai. The road went under construction in B.E.2477. At that time, only the strong and devoted made the minimum five hours hike up the mountain to Doi Suthep through dense tropical forest. At that time, the government could not raised sufficient money to build the road, so they called upon Kruba Srivichai to help. He sent words far and wide, and because of his great popularity, volunteers came from all over Thailand to lend a hand to the effort. It was said that as many as 3,000 to 4,000 people a day came to build the road, which was originally paved in stone.
Because so many volunteers heeded his call, Kruba’s original request for each village group to
complete 50 feet of road was decreased to 10-15 feet. Day by day, a massive volunteer workforce cleared the area and set stones on the roadway. The road was completed in 5 months and 20 days. Kruba Srivichai was the first to inaugurate the opening of the road on 30 April, B.E.2478.
Kruba Srivichai passed away in B.E.2481 at the age of 60 and he was given the title "Nak Bun Haeng Lanna", which may be translated as The Lanna Saint.
