In the book Stillness Flowing, about Ajahn Chah's life and teaching, there's a chapter(page 57) that talks about both sects. Historicaly how and why Dhammayut sect was created and the differences between them. Basically the founders of the thai forest tradition Ajahn Khao and Ajahn Mun were from Dhammayut sect and most Mahanikaya monks who decided to train under them had to reordain in the Dhammayut order.That was done for concerns that their ordination may not be legitimate or that thay have broken too many vinaya rules and to make sure that their ordination is pure.paul wrote: ↑Fri Jul 20, 2018 10:13 pmCould you give your take on how the Thai Forest Tradition fits into this?tbeaudoin wrote: ↑Fri Jul 20, 2018 6:38 pm (1) Much of Thai Buddhist practice - among both laity and monastics - had by the 1800s become infiltrated with many indigenous animistic beliefs and practices, as well as some beliefs and practices from Hinduism and Mahayana Buddhism. Many kingdoms in Southeast Asia converted to Hinduism, then to Mahayana Buddhism, and lastly to Theravada Buddhism. Summary: Dhammayut was founded in order to purify Buddhism from animistic, Hindu, and Mahayana beliefs and practices.
Ajahn Chah visit Ajahn Mun and asked questions for 3 days but he didn't change his leanage. And after that, inspired by the strict following of vinaya and the dhutanga practeces, he basically introduced the thai forest tradition to Mahanikaya order.
Luang Por Chah’s visit to Luang Pu Mun was then not simply that of a
young tudong monk to the father of the Thai Forest Tradition, but also
that of a Mahānikāya monk to a Dhammayut monastery. During his brief
visit, some of the younger resident monks urged Luang Por to switch to
the Dhammayut Order as they had done, but he remained unmoved. Most
probably, he considered a change of affiliation to be ungrateful or disloyal.
Luang Por himself never revealed his thoughts on the matter. What is
known is that one of the questions that he asked Luang Pu Mun during
his visit was this central one of re-ordination. Was it necessary for one
intent on realization of the Dhamma? Luang Pu Mun put his mind at rest:
no, it was not.
It has been recorded that, prior to Luang Por’s visit, one of Luang Pu Mun’s
senior disciples had a meditative vision in which he saw Ubon split off
from the rest of Isan. Luang Pu Mun apparently considered this a sign that
Ubon would not be a stronghold for the Dhammayut forest monks in the
future. It is said that he recognized in Luang Por Chah the one who would
introduce the Forest Tradition into the Mahānikāya Order and establish
monasteries in Ubon.
