True enemies may be easy to spot, but what about "near enemies"? If near enemies were people, we might call them "frenemies". A near enemy is a subtle quality that we may miss or confuse as useful or helpful when, in fact, it can become an obstacle to our mindfulness practice that is hidden from us or in disguise.
Compassion, lovingkindness, appreciative joy, and equanimity are beneficial mental states that could be considered four complimentary "flavors of love". Together they form a firm foundation upon which authentic love can take solid root in a way that is boundless & indestructible. We can cultivate these qualities through a dedicated mindfulness practice.
