What does it technically mean to have a “beautiful mind” in meditation—beyond vague metaphores or mysticism. Defining the Beautiful Mind When modern teachers describe deep samatha (concentration) meditation as “beautiful,” they speak in mystical metaphors. However, real Theravāda Buddhism involves the Abhidhamma. The Abhidhamma is not for scholarly proliferation. It is for knowing how the mind works and applying the mind in that way. The Abhidhamma provides a precise definition: sobhāna cetasikā, or beautiful mental factors.
