Mud Pies and Holidays By the Sea: Vintage CS Lewis

Vintage St Clive from today's Readings for Reflection in A Guide to Prayer:

If there lurks in most modern minds the notion that it's a bad thing to desire one's good and earnestly hope for enjoyment, it is because it has crept in from the teachings of Immanuel Kant and the ancient Stoics. Certainly, it has no part in the Christian faith. Indeed, if we consider the unblushing promises of rewards promised in the Gospels, it would seem that our Lord finds our desires not too strong, but too weak. We are half-hearted creatures, fooling about with drink and sex and ambition when infinite joy has been offered to us. We are far too easily pleased, like an ignorant child who goes on making mud pies in a slum because he cannot imagine what is meant by an offer of a holiday at the sea. C. S. Lewis, The Weight of Glory (New York: MacMillan, 1980), p136 (I think)

Am I missing any holidays by the sea? I wonder if Jesus can use the mud from my pies to heal my blindness, too.
