The perfect mystic is not an ecstatic devotee lost in contemplation of Oneness, nor a saintly recluse shunning all commerce with mankind, but "the true saint" goes in and out amongst the people and eats and sleeps with them and buys and sells in the market and marries and takes part in social intercourse, and never forgets God for a single moment.
A customer is the most important visitor on our premises. He is not dependent on us. We are dependent on him. He is not an interruption in our work. He is the purpose of it.
