O Holy Spirit, descend plentifully into my heart. Enlighten the dark corners of this neglected dwelling and scatter there Thy cheerful beams. --Augustine
"When the divine descent occurs, it's a little like putting seasoning into a pot of soup. Or maybe prozac into a skull full of neurons. That is, when you sprinkle salt into the soup, you can't just affect the beans but not the meat. Likewise, when you sprinkle an SSRI into a brain, it gets into everything, which is why the effects are nonlinear and unpredictable in their details. Also, it takes a while for the spices -- or the prozac -- or God -- to penetrate and macerate into the substance."
