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.
