1. Our human concept of glory. For us glory is the measure of our own value. A recognition given by others giving us integrity, stability, happiness and harmony. In its earthy meaning, glory is such a power for which you do not have to fight again and again. Our longing desire for glory may accompany us as an insatiable and burning feeling through a whole unsatisfied, and (according to our measures) inglorious life.

2. The real nature of Glory. The Glory of God is the exact opposite of glory considered in its earthy meaning: it is the light and love flowing out of Him to those who become part of the community of God. With His Glory, God does not receive but gives. However, God does not overspread us with His Glory according to our merits but because it is the very nature of His existence. By pouring out His Glory on us, God gives US integrity, stability, happiness and harmony if we are open to a connection with Him. The human soul, accepting the Glory of God does not only absorb it (as the devil does) but becomes alive and begins to reflect the Glory of God through its entire life.

3. The Glory of the Trinity. Glory radiates from God. However, the flow of Glory and its power (that changes those human souls, which are open to become connected with God and Christ) are very important characteristics of the Holy Spirit. The Holy Spirit may be the part of the Trinity that is the least possible to be characterized using human words. On one hand, the drift of the Holy Spirit may be so obvious and overwhelming that man getting quite far away of his previous self may take plenty of actions one after the other he could never ever imagine before. On the other hand, the Holy Spirit works in us in the silence of every day, too. Thus the Holy Spirit is the "direct representation" of the Glory of God for the souls that have not become united with Totality yet, whom it resurrects in Christ and enables to live a life reflecting the Glory of God.
