The world around us, the world of nature is our best teacher. One has only to sit quietly in a garden in spring, in the early hours, to become aware of an intricate trajectory of invisible lines criss-crossing the garden as birds flit and whirr about their tasks, never colliding. We, too, are birds of passage and yet we are a part of the whole. We move through time, yet eternity is all about us. St. Bernard of Clairvaux wrote:
What I know of the divine sciences and holy scripture, I learnt in the woods and fields. I have had no other masters than the beeches and the oaks. You will learn more in the woods than in books. Trees and stones will teach you more than you can acquire from the mouth of a teacher.
Which also is why, whenever we can, it is good to meditate out of doors, in a garden or a park, aware of all life around us learning, in the words of William Blake, to ‘see a world in a grain of sand and eternity in an hour’.
