Love of light is full of potential energy and ubiquitous.
Shadows, if any, are of human and imperfection caused by the mask/bias in the lower physical realms.
Selfish love is conditioned to require the return of desires and affections - will cause shadow of pain by human if return is not proportional to what has been expected of.
Unconditioned noble benevolent unselfish love never has shadow and is existed in the higher consciousness Mind.
