"The loving affairs between Krishna and the gopis in Vrindavana are also transcendental. They appear as ordinary lusty affairs of this material world, but there is a gulf of difference. In the material world there may be the temporary awakening of lust, but it disappears after so-called satisfaction. In the spiritual world the love between the gopis and Krishna is constantly increasing. That is the difference between transcendental love and material lust. The lust, or so-called love, arising out of this body is as temporary as the body itself, but the love arising from the eternal soul in the spiritual world is on the spiritual platform, and that love is also eternal. Therefore Krishna is addressed as the ever green Cupid."
(Teachings of Lord Caitanya, Chapter 31)
