Phra Luang Phor Kasem was born on Wednesday, 28th November B.E.2455 at Na Kao Muang Village, at the edge of the Wang River in Jangwat Lampang. His father was a northern prince named Chao Noi Noo and his mother was Chao Mae (a lady with high birth) Bua Jon Na Lampang. His parents were descendants of Chao Boonyawat Wong Manit, the last ruler of Lampang.

He became a novice monk in B.E.2468. After the dead of his uncle, the abbot of Wat Bunyeun, In B.E.2470, he went to Bangkok, Wat Setuwan to study Pali language. He returned to Lampang and furthers his Pali studies in Wat Seelom and Wat Bunyawaht.

In B.E.2475, he passed his Pali examination with good results and came in first in class at Wat Setuwan. In B.E.2476, he was ordained as a monk at Wat Bunyeun at the age of 21 years old. His preceptor was Dhan Chao Khun Tammajindah. His ordained name's was Kemagoh Pikkhu.

After he entered monkhood, Luang Phor Kasem went to Jangwat Chiangrai to further his Pali studies. He met Luang Phor Krubah Gaen, a very famous monk in North Thailand who was a Tudung monk (forest monk), very good in Sammahdti. Luang Phor Kasem became a disciple of Phra Krubah Gaen and went Tudung with his teacher in forests and cemeteries.

When the abbot of Wat Bunyeun passed away, Phra Dtomkum became the new abbot. After some time, Phra Dtomkum left the temple and the post of abbot at Wat Bunyeun because of boredom. The villagers invited Luang Phor Kasem to return to Lampang to be the new abbot of Wat Bunyeun.

Luang Phor Kasem continues his learning in Dhamma and Sammahdti practice even when he was the abbot. The more he trained, the more realized that life is uncertain. His duties as the abbot, kept him rather busy and finally in B.E.2492, he left Wat Bunyeun, and went to stay at Sasahn Sahlahwangthan (a cemetery at another place in Lampang). Luang Phor Kasem was determined to practice the highest Sammahdti at the cemetery. He would sit in front of the burial place and watch the burning of corpse. Whether in hot sun or raining, Luang Phor would just sit quietly and watched the corpse being burned to ashes.

Luang Phor Kasem ever sat in Sammahdti for as long as 3 months, without shelter under hot sun or heavy rain. Even his robes were wet by the rain or during cold season, when the cold wind blows, Luang Phor Kasem would just sit quietly and not complain and asked for anything. He had let go of everything and steadfast in his practice of Dhamma and Sammahdti. He ever goes without food for 49 days.

Since B.E.2514, Luang Phor Kasem only bathed once a year, but there is no stench or foul odor from his body, even his sweat was pouring under the hot sun. More surprisingly, without shelter and mosquito net, Luang Phor Kasem never suffered a bite from mosquito at the cemetery.

Luang Phor Kasem carried nothing with him. His only possession was an alm bowl, his robe which he was wearing and a piece of human bone for him to practice Sammahdti. He did not even have any footwear.

Luang Phor Kasem ever mentioned that he is a forest monk and does not require any possession. He was contented with a piece of robe covering his body. Whatever things that the layman gave to him, Luang Phor Kasem would give away to other monks.

Luang Phor Kasem never used a pillow to sleep, because to him, a pillow is a luxury. Luang Phor Kasem would sleep with his body in full prostrate position and would sleep at the same spot where he sat in Sammahdti.

He was very determined to find the truth of life. He asked for nothing in life though he can enjoy the luxuries in life as he was the descendants of royal blood in Lampang. Luang Phor Kasem passed away in B.E.2538 at the age of 83.

His followers later established Luang Phor Kasem Foundation and used the yields from its investment to help the poor and many academic institutions.
