what is the relationship between love and enlightenment? is love a necessary component of wisdom

Is this a general question or directly related to the book?

in a way both it deals with one of the themes of the novel which is love.

do you need me to re phrase it?

I think to achieve enlightenment Siddhartha had to let go of the desire aspect of "love". Enlightenment comes from a sense of detachment to desire and even the earthly concept of love. The word "love" means a very different context in the realm of Buddhist enlightenment.
