The perfect mystic is neither an ecstatic devotee lost in contemplation of Oneness nor a saintly recluse shunning all commerce with mankind. The true saint goes in and out among the people, eats and sleeps with them, buys and sells in the market, marries and takes part in social intercourse, and never forgets God for a single moment.
