The hymn below both encapsulates and describes precisely what it is like to meet the indescribable Divine Light:
“What is this awesome mystery that is taking place within me?
I can find no words to express it:
My poor hand is unable to capture it,
In describing the praise and glory that belong
To the One who is above all praise,
And who transcends every word . . .
My intellect sees what has happened,
But it cannot explain it;
It can see, and wishes to explain,
But can find no word that suffices,
For what it sees is invisible and entirely formless,
Simple, completely uncompounded,
Unbounded in its awesome greatness.
What I have seen is the totality recapitulated as One,
Received not in essence but by participation.
It is just as if you lit a flame from a live flame:
It is the entire flame you receive”
Symeon the New Theologian, Hymn 1.
