Love should be treated like a business deal, but every business deal has its own terms and its own currency. And in love, the currency is virtue. You love people not for what you do for them or what they do for you. You love them for the values, the virtues, which they have achieved in their own character.
Spirituality is not a question of morality, it is a question of vision. Spirituality is not the practising of virtues - because if you practise a virtue it is no longer a virtue. A practised virtue is a dead thing, a dead weight. Virtue is virtue only when it is spontaneous; virtue is virtue only when it is natural, unpractised - when it comes out of your vision, out of your awareness, out of your understanding.
