What is this line basically saying:

You are a body, I am its life, I am your recognization.

Is it basically saying that without you I do not exist. You are everything of mine.

What else could I add to this?

Taken out of context, it's nearly impossible to discern its meaning.

I think it is referring to teo lovers, in which the girl is saying to her mate that she is incomplete without him. Could this work out well to discern the meaning?

Possibly -- but I can't tell without knowing more.

The line you provided seems to convey the idea that the speaker perceives themselves as the life or essence of the listener's body and seeks recognition or acknowledgement from them. It implies a sense of dependency or interconnectedness, with the speaker suggesting their existence is dependent on the listener's recognition.

To further elaborate on this line, you can consider expanding on the emotional aspect of this connection. For example, you could explore themes of identity, longing, or the significance of mutual acknowledgement. Additionally, you might want to provide more context or explore the potential underlying meaning behind this statement, as interpretations can vary depending on the perspective and intent of the speaker.
