That which breaks the heart or brings despair is a difficulty or a trouble through which we cannot see; this means that our trouble in life is always lack of light and nothing else; that every difficulty can be solved, and if we understand the nature of our difficulty, we can see our way through. It is the lack of light which prevents our seeing into our trouble, as well as the way out of it, and it is the light which gives us the power to see into our difficulty as well as showing the way out of it.
