“Sweet are the uses of adversity,
Which, like the toad, ugly and venomous,
Wears yet a precious jewel in his head;
And this our life, exempt from public haunt,
Finds tongues in trees, books in the running brooks,
Sermons in stones, and good in every thing.” – William Shakespeare
Can you find the sermon in the stone?
If not, look a little closer and realise everything and everyone around you is your teacher.
