Love is as simple as the absence of self given to another. God, when invited, fills the void of any unrequited love; hence loving is how one is drawn closer to God no matter its most horrific repercussions.
Detachment is not the absence of emotion, it is the process of becoming one with the Oneness that is the Universe. To be detached, is to realize that the fullness of all there is, is too much to react to with just one emotion, one thought, or any bias. To be detached, is to acknowledge all, without owning any of it. To be detached, is to summon forth the whole entirety of understanding, to the fragment that is the void.
