What will you find behind the door that is one door away from Heaven? […] If your heart is closed, then you will find behind that door nothing to light your way. But if your heart is open, you will find behind that door people who, like you, are searching, and you will find the right door together with them. None of us can ever save himself; we are the instruments of one another's salvation, and only by the hope that we give to others do we lift ourselves out of the darkness into light.
chapter 73, pp. 604, 605 - One Door Away from Heaven (2001)
