One of my favorite authors is Annie Dillard.  I have never forgotten the wonderful passage in her book,  Pilgrim at Tinker Creek, where she mentions Martin Buber who quotes an Hasidic master:

Sparks of their Souls

When you walk across the fields with your mind pure and holy, then from all the stones, and all growing things, and all animals, the sparks of their soul come out and cling to you and then they are purified and become a holy fire in you.
