When it comes to love, the mind and heart are rarely united. If love is no longer present, the mind tries to forget love to protect the body, to move on to limit pain and allow space for healing, but the heart keeps love close despite the pain.
It reminds the mind of a love that is lost. The stronger the love, the more intense the struggle until there is a permanent place where this love resides, as a constant reminder of what real love is. Only at this point do the mind and heart reunite in its search for love.
