Dhammakāya meditation is an approach to Buddhist meditation (especially samatha and vipassana) taught by Phramongkolthepmuni in the early 20th century.
The identifying feature of Dhammakaya meditation is the meditator's attention towards the centre of the body as two finger breadths above the navel. The promoters of this approach say this is the same point as the end-point of the deepest breath in mindfulness of breathing meditation (Anapanasati), although the early Buddhist texts do not mention any such physical location. It is called an approach rather than a method because any of the forty methods of samatha meditation mentioned in the Visuddhimagga can be adapted to it.
