Profound and simple. A book I return to often. A favorite quote from the book that talks about children and parents. A bit where the author, Khalil Gibran, talks about Love.

For even as love crowns you so shall he crucify you. 
Even as he is for your growth so is he for your pruning.
Even as he ascends to your height and caresses your tenderest branches that quiver in the sun,
So shall he descend to your roots and shake them in their clinging to the earth.
