This is one of my many favourites from the book.
…he said one should keep the intellect satisfied yet be careful not to spoil it. It was one of his rules:
“Intellect and love are made of different materials. Intellect ties people in knots and risks nothing, but love dissolves all tangles and risks everything. Intellect is always cautious and advises, ‘Beware too much ecstasy,’ whereas love says, ‘Oh never mind! Take the plunge!’ Intellect does not easily break down, whereas love can effortlessly reduce itself to rubble. But treasures are hidden among ruins. A broken heart hides treasures.”
