Humility is crucial in healthy bonding. Arrogance divides people. Preoccupation with your own desires and needs separates you from others. Humility allows you to appreciate another person and bond with him. Bonding that is just an extension of your own needs is only bonding tighter with yourself. Healthy bonding is the union of two distinct people, with independent personalities, who join for a higher purpose than satisfying their own needs.
True humility comes from recognizing and acknowledging G‑d in your life. Am I aware of the third partner - G‑d - in bonding? And that this partner gives me the capacity to unite with another, despite our distinctions.
Exercise for the day: When praying acknowledge G‑d specifically for helping you bond with others.
