Yūgen 

Isn't everything we see merely a whisper of that infinity we cannot see? The foot of a mountain disappearing behind the fog, the last moment of a ship vanishing on the horizon... What is revealed to us is not the entire truth, but only that mysterious veil that hints at its existence. The deepest beauty is that moment itself, the one we cannot fully comprehend, the one we cannot put into words. If we knew everything, if we saw everything clearly, would there still be room in our hearts for that sweet ache, that awe? Perhaps truth lies in the gracefulness with which it does not fully reveal itself to us.
