The unknown cannot be spoken about using direct and proper terms because there are NO direct or proper ways to describe it
IMHO
And why do you look at the speck in your brother's eye, but do not percieve the plank in your own eye? Or how can you say to your brother, "brother let me remove the speck from your eye", when you yourself do not see the plank that is in your own eye?-Yeshua ben Yoseph
