Vision is beyond understanding

Daniel 8:15-27
While I, Daniel, was watching the vision and trying to understand it, there before me stood one who looked like a man.
And I heard a man’s voice from the Ulai calling, “Gabriel, tell this man the meaning of the vision.”
“The vision of the evenings and mornings that has been given you is true, but seal up the vision, for it concerns the distant future.”
I, Daniel, was worn out. I lay exhausted for several days. Then I got up and went about the king’s business. I was appalled by the vision; it was beyond understanding.  
Gabriel: This is the first time God's messenger-angle is named in the Bible. It was Gabriel who appeared to Zechariah, father of John the Baptist, and again to Mary before the birth of Jesus.
The end:  This usually refers to the winding-up of history, and God's final judgment. But verse 26 relates the vision to the distant future, and 19 to the period when the suffering will be over. The Bible writers often seem to step clear of time, and view contemporary and future events as one aspect of the total, final events of 'the end'.
Why?
Suffering these vision, Daniel terrified and got sick for several days. Knowing the vision of future bring the burden and understanding. Only the man who has the grace from the Lord may watch the vision.
Daniel told us the vision let us know that God is the master of history. He knows what will happen and who will raise and wipe out.
Distant future is unknown but we know that God only one who is the Lord of future.
How?
I know there is a judgment at the end, everyone have to face what he have done on earth. May my mind and my heart be holy and do the right things.
