If so many generations had found solace here, might I also? The holiness of the psalms came to seem like that of a stone that has been held in the palm by countless ancestors, illustrating the difference between what the poet Galway Kinnell has termed the "merely personal," or individual, and the "truly personal," which is individual experience reflected back into community and tradition.
