In neoplatonism, what are two important elements?1

Neoplatonism is a dynamic philosophical tradition that was founded by Plotinus and greatly influenced by Plato. In Neoplatonistic philosophy, all reality stems from a single principle, "the One". Neoplatonists generally shared basic beliefs about the nature of reality, but there were significant differences in their specific views, making it difficult to distill down this philosophy to one set of beliefs.
