The Dhammakaya Movement or Dhammakaya tradition is a Thai Buddhist tradition which was started by Luang Pu Sodh Candasaro in the early 20th century. It is connected to several temples which refer back to Wat Paknam Bhasicharoen in Bangkok for their ancestry. The movement practices Dhammakaya meditation (Vijja Dhammakaya), a form of meditation which scholars have linked to the Yogavacara tradition. Central to the movement is the idea that Dhammakaya meditation was the method through which the Buddha became enlightened, a method which was forgotten but has been revived by Luang Pu Sodh Candasaro.
Scholars have theorized that The Dhammakaya movement has its roots in the Yogavacara tradition (also known as tantric Theravada). The movement was started by Luang Pu Sodh Candasaro in the early twentieth century. The movement is connected to several temples which refer back to Wat Paknam Bhasicharoen in Bangkok for their ancestry. Luang Por Dhammajayo and Luang Por Dattajivo, the current abbot and vice-abbot of Wat Phra Dhammakaya, were students of maechi (nun) Chandra Khonnokyoong. She in turn was a student of Luang Pu Sodh Candasaro, the meditation master who developed Dhammakaya meditation and the abbot of Wat Paknam. Other temples, such as Wat Luang Phor Sodh Dhammakayaram, also have their roots in Wat Paknam. After discovering the Dhammakaya meditation approach, Luang Pu Sodh first taught it to others at Wat Bangpla, Bang Len District, Nakhon Pathom. When Luang Pu Sodh was given his first position as abbot at Wat Paknam, Dhammakaya meditation has been associated with this temple ever since. Since 1959, Dhammakaya meditation has been taught by Luang Pu Sodh's students at Wat Paknam Bhasicharoen, Wat Phra Dhammakaya, Wat Luang Por Sodh Dhammakayaram, and at Wat Rajorasaram, as well as the respective branches of these temples. Apart from these temples, there are also several other centers that practice in the tradition of Luang Pu Sodh.
