Affinity is never identification, nor does it go quite so far as empathy. You remain very much yourself when you have affinity for something but you also feel the essence of the thing for which you have affinity. You remain yourself and, yet, you draw closer to the object for which you have affinity. It is not a binding quality.
There are no strings attached when affinity is given. To the receiver it carries no duties and no responsibilities. It is pure, easy and natural and flows out from you as easily as sunlight flows from the sun.
