"Verily, we have caused it to descend on the night of power. And who shall teach thee what the night of power is? Therein descend the angels and the spirit by permission of their Lord for every matter." (127: 1, 2, 4.)
The writer has posted the above verses and has commented that the Quran was revealed in one night. This is just his view based on his limited data! The whole Quran has not been mentioned here. Every person knows that the Quran was revealed over a period of 23 years and the revealing here refers to the descent on one night. One particular revelation is being talked about in this verse and the whole Quran has not been mentioned which somehow the writer understood.
The writer has once agian made the same point of God being limited to one place because coming down would mean that He is above. This is the Islamic belief, that God is above the heavens and His knowledge is everywhere unlike his kinetic energy god. Kinetic or cosmic energy is due to God and is not god.
Holy spirit is a Christian terminology and the Quran calls it "Rooh ul Qudus". It is another name of angel Gabriel. the writer did not know this and if he had knon this, he wouldn't have written this point.
