I value friendship more highly than love, of which it is a part, perhaps the greatest part. It is free of the tiresome jealousies and overheated humours of love and does not need constant validation. David Whyte writes beautifully about it:
Friendship is a mirror to presence and a testament to forgiveness. Friendship not only helps us see ourselves through another’s eyes, but can be sustained over the years only with someone who has repeatedly forgiven us for our trespasses as we must find it in ourselves to forgive them in turn. A friend knows our difficulties and shadows and remains in sight, a companion to our vulnerabilities more than our triumphs, when we are under the strange illusion that we do not need them. An undercurrent of real friendship is a blessing exactly because its elemental form is rediscovered again and again through understanding and mercy. All friendships of any length are based on a continued, mutual forgiveness. Without tolerance and mercy all friendships die.
The dynamic of friendship is almost always underestimated as a constant force in human life: a diminishing circle of friends is the first terrible diagnostic of a life in deep trouble: of overwork, of too much emphasis on a professional identity, of forgetting who will be there when our armored personalities run into the inevitable natural disasters and vulnerabilities found in even the most average existence. But no matter the medicinal virtues of being a true friend or sustaining a long close relationship with another, the ultimate touchstone of friendship is not improvement, neither of the other nor of the self, the ultimate touchstone is witness, the privilege of having been seen by someone and the equal privilege of being granted the sight of the essence of another, to have walked with them and to have believed in them, and sometimes just to have accompanied them for however brief a span, on a journey impossible to accomplish alone.

John O'Donoghue on Friendship
In the Celtic tradition, there is a beautiful understanding of love and friendship. One of the fascinating ideas here is the idea of soul-love; the old Gaelic term for this is anam cara. Anam is the Gaelic word for soul and cara is the word for friend. So anam cara in the Celtic world was the “soul friend.” In the early Celtic church, a person who acted as a teacher, companion, or spiritual guide was called an anam cara. It originally referred to someone to whom you confessed, revealing the hidden intimacies of your life. With the anam cara you could share your inner-most self, your mind and your heart. This friendship was an act of recognition and belonging. When you had an anam cara, your friendship cut across all convention, morality, and category. You were joined in an ancient and eternal way with the “friend of your soul.” The Celtic understanding did not set limitations of space or time on the soul. There is no cage for the soul. The soul is a divine light that flows into you and into your Other. This art of belonging awakened and fostered a deep and special companionship.
