1. The Accomplished One (Araham)
Araham means that the Blessed One is worthy of all veneration because He has destroyed all defilements – greed, hate, delusion, conceit, speculative view, skeptical doubt, mental torpor, restlessness, shamelessness and lack of moral dread. Therefore, He is far away from all internal conflicts and devoid of secret evil-doing.

2. The Perfectly Self-Enlightened One (Sammasambuddho)
The Lord Buddha is the Perfectly Enlightened One because He has known all things (Nyeyadhamma) rightly by Himself. In fact, He has of Himself known all the things, knowable things as knowable, removable things as removable, realizable things as realizable, and things that may be developed as such.
There are five kinds of Nyeyadhamma: a. Consciousness and mental concomitants - mental phenomena and material qualities grouped as the "conditioned" (Samkhara), b. Mutable material qualities (Vikara Rupa), c. Four characteristics of material qualities (Lakkana Rupa), d. All names and terms which make known and idea or notion of attributes of a thing which is made known (Panntti), e. Nibbana, the ultimate goal, i.e. the dhamma which can be gained by the complete destruction of all forms of craving.
