"The One Thus-Gone who Understands Clearly, Enjoying the Radiant Light of Purity" (de-bzhin gshegs-pa tshang-pai od-zer rnam-par rol-pas mngon-par mkhyen-pa, Tathagathabrahamajyotivikriditabhijna) sits in the south-east in the heavenly field 'pervaded by purity.' He is white and holds a lotus and a pool of light. The epithet "One Thus Gone" is ascribed to this and the following full Awakened Being, but it should be remembered that it applies equally to all thirty-five Awakened Ones.
"Purity" refers to his primordial awareness as noted before; "Radiant Light" refers to his excellence, his great ability that is extremely clear; "Enjoying" indicates his function of benefiting sentient beings through such feats as miraculous emanations; and through his primordial awareness of mind he clearly understands such things as the means for being of benefit.
