Like the air that circles by,
For without it we shall die,
Your beloved presence, here,
Indispensable, my Dear,
When I know that you're not near,
Black, dark Shadows break all Light,
Life becomes a useless sight,
In the sadness of the night.

Without you, there is no me,
Being has just stopped to be,
Oneness is so obsolete,
Two hearts should as one now beat,
Only Love can Life complete.
