Genuine compassion must have both wisdom and loving-kindfulness.

Compassion is an aspiration, a state of mind, wanting others to be free from suffering. It's not passive -- it's not empathy alone -- but rather an empathetic altruism that actively strives to free others from suffering. Genuine compassion must have both wisdom and lovingkindness. That is to say, one must understand the nature of the suffering from which we wish to free others (this is wisdom), and one must experience deep intimacy and empathy with other sentient beings (this is lovingkindness)."
