A Sufi teacher of my acquaintance said in my hearing when someone asked him to talk about God: ‘It would be an insult to God to speak of him to you; and it would be valuing me too highly to assume that I dared to talk of God.’
Most people’s ‘God’ is their vanity, their own self-conceit, their epithet, used for emotional and intellectual purposes. It is important to speak of a thing, let alone God, with reserve unless it be warranted.
