Someone has a great fire in his soul and nobody ever comes to warm themselves at it, and passers-by see nothing but a little smoke at the top of the chimney and then go on their way.

One may have a blazing hearth in one's soul and yet no one ever came to sit by it. Passers-by see only a wisp of smoke from the chimney and continue on their way. // There may be a great fire in our hearts, yet no one ever comes to warm himself at it, and the passers-by see only a wisp of smoke.
