Enlightenment a.k.a. Unification
Stardate 55288.388
Which term we would use or prefer would depend on the definition and the cultural background. Within cultures wherein Enlightenment is a term already used for various things or even just one, it is certainly inapropriate to quarrel about 'what' Enlightenment now is, or what 'true' Enlightenment is once there is no Philosophical basis to 'wander'. (To wander: To move around together within a mutual understanding of what meaning which term does imply, alias: Peaceful, not restrained to the matter per-se)
Ergo: Contemplating upon the meaning of the Enlightenment introduced here (Shin-Gouryuu) the resolve must be that it is 'not' comparable to the Buddhistic form of Enlightenment (Satori). Satori is the result of schooling the own mind and meditation - it is a menthal status one may achieve - Shin Gouryuu on the other end is about the individuals relationship to the true and living God.
This way must be walked with the true and living God on mind and is to take one to the true recognition of that God. That way knows multiple stages of 'Enlightenment'. It takes one to Christ, then to the true church alias that which is 'the true Body', and finally the Unification as 'end-gate' into the Higher form of existence that He provides.
The 'Enlightenment' (ju-kou - sorry, I don't speak Japanese. I'm just guessing) is the 'being filled with the Light' as a later stage of the way beyond that Gate. But Enlightenment in the sense of Understanding the essence/being of the Universe does already begin with learning of God and leads within Unification into state that is what it says: Unification with the All-Surrounding spirit.
'Tai Chi' (chinese: Eternal Harmony or something) can be used as supplementary example. Tai Chi (Chuan) is a physical praxis that so over time yields experiences that then are applicable within the physical. It is 'gaining Harmony' via workout. The recognition of the existence and identity and ideology of God is however a matter of understanding - there equally leads into "higher Ranks" we might say but does through the New Covenant (Baptism) and finally Unification (shin-gouryuu) create fundamental changes that are given as cause to an effect. Needless to say that there are ways to see that as a bottom where now one with the ambition to practice Zazen/find Satori can grow in ranks, as opposed to but maybe not entirely unequal to for instance using Marijuana.
