Bua observes the essential enduring truth of the sentient being as constituted of the indestructible reality of the "citta" (heart/mind), which is characterized by the attribute of Awareness or Knowingness. This "citta", which is intrinsically bright, clear, and aware, gets superficially tangled up in samsara but ultimately cannot be destroyed by any samsaric phenomenon. Although Bua is often at pains to emphasise the need for meditation upon the non-Self ("anatta"), he also points out that the "citta", while getting caught up in the vortex of conditioned phenomena, is not subject to destruction as are those things which are impermanent, suffering, and non-Self (anicca, dukkha, anatta). The citta is ultimately not beholden to these laws of conditioned existence. The "citta" is bright, radiant, and deathless, and is its own independent reality.
