The capacity to be alone is the capacity to love. It may look paradoxical to you, but it’s not. It is an existential truth: only those people who are capable of being alone are capable of love, of sharing, of going into the deepest core of another person—without possessing the other, without becoming dependent on the other, without reducing the other to a thing, and without becoming addicted to the other. They allow the other absolute freedom, because they know that if the other leaves, they will be as happy as they are now. Their happiness cannot be taken by the other, because it is not given by the other.

I agree with this somewhat but at the same time, I think there can be selfish, dependent love. Two people can be deeply in love and have an unhealthy, possessive relationship. However, I think that this quote is hugely important when it comes to working on healthy relationships, between family members, friends, and couples.
