A blade of grass is a miracle, it’s more complicated than a skyscraper. Imagine a skyscraper would grow in your backyard; a blade of grass makes a skyscraper into nothing, it’s so complicated. A skyscraper can’t grow. This can grow too, it gets bigger and bigger.

Miracles of miracles in one blade of grass. And that causes people, even of smaller stature, to become aware of Hashem and full of joy. — True Happiness (#685)
