Dharma

A polysemous term. Dharma with the upper case D refers to teachings of the Buddha, a synonym for Buddhadharma. In the lower case, it refers to all phenomena in the mundane world, i.e., the five aggregates or the eighteen elements. A deeper meaning of dharma refers to the limit of all phenomena, the root source or origin of all phenomena, i.e., the Tathagatagarbha, as in dharmadhātu (dharma realm), dharmakāya (dharma body).
