How do the Lord's words of John 12:23 bear immediate reference to te seeking Greeks?

The Son of Man was a prophetic term.

Jesus was speaking of His death. Jesus believed that once He was killed the death that was prophesied concerning Him, the works that His Father sent Him to do would be finished, and then He would be glorified, but Jesus' work was not finished.

Jesus had to descend to hell and free all the lost souls, and bind the devil first, then His work would be finished and He would be glorified and be seated at the right hand of His Father.

The hour referred to His time had come to die, as Jesus said, earlier there are yet 4 months to harvest, my time is not yet..

And when Jesus told Judas do what you must do and do it quickly, as soon as Judas walked out the door Jesus exclaimed "Now I be glorified"

Jesus also told us to make a memorial of Mary Magadalene because she anointed the body of Jesus at the hour of his death.

Hour means the time of His death is now at hand, (the actual events leading up to His death), not the actual time his death will take place.

And after Jesus died on the cross, three days later Jesus was seen alive again.

Jesus let Himself be seen alive again, to prove that His words were true.

We are spirit living in flesh bodies, the body may die, but the spirit is "born again".

No one has ever died, no not one, this is why Jesus said "let the dead bury the dead", because if you believe that the body is your life than you are already dead, because you would not believe in the words of God the Father only begotten Son, an angel, the Christ, a Son of God, born into the flesh.

I have no idea what you are asking.... Jesus is stating the fact that his ministry is over and he will be going to Heaven... that is what is meant by Going to Glory... in reference to a believers mortal end.
