John Milton said this quote

So dear to heaven is saintly chastity, That when a soul is found sincerely so, A thousand liveried angels lackey her, Driving far off each thing of sin and guilt, And in clear dream, and solemn vision Tell her of things that no gross ear can hear, Till oft converse with heavenly habitants Begin to cast a beam on the outward shape, The unpolluted temple of the mind, And turns it by degrees to the soul's essence, Till all be made immortal
