pairs. These inner bodies ultimately lead to the Dhammakāya, the Dhamma-body, which is described as the shape of a Buddha sitting within oneself. The vipassanā stage of Dhammakaya meditation is done by contemplating the three marks of existence of the lower mundane inner bodies after reaching the Dhamma-body. Dhammakaya meditation at the higher levels is also believed to bring forth abhiññā, mental powers that can be used for the benefit of society at large. Examples include stories of miraculous events such as Luang Pu Sodh performing healings, and meditation stopping the Allies from dropping an atom bomb on Bangkok due to the Japanese occupation of Thailand in World War II. Similarly, Wat Phra Dhammakaya has included claims of miracles in its PR along with images of amulets with miraculous powers.

Some of the beliefs and practices of the Dhammakaya tradition – such as about Niṛvāna, "true self" and meditation – have been criticized as allegedly opposing or rejecting the mainstream Theravāda teachings and practices by traditional Thai Buddhist institutions. According to Seeger, the bulk of Thai Theravāda Buddhism – including a number of Thai scholars, academics, monks and social critics – reject the true-self teaching of Dhammakaya,
