If I could explain it in only one word, there is not enough time in the world to come up with that word. 

The flaming passion that sets my heart alight, like several thousand stars in the night.

The love I feel for her, the love she feels for me. 
There is not enough words known to mankind for she and I, not enough songs in the sky or in our soul.

It's my burning heart that gives me this melody.

Sing to me the song of these tears, the song that will set my fears,
Sing to me the song of my heart, that which beats every start,
Sing to me the song of love.
