Buddha told a parable in sutra:

One day, walking through the wilderness, a man stumbled upon a sleeping tiger. As he tried to sneak past, the tiger awoke, and began to give chase.

The man took flight, running as fast as he could until he found himself at the edge of a high cliff. Desperate, he climbed down a vine and dangled over the jagged precipice. As he hung there, two mice, one white and one black, appeared from a hole in the cliff and began gnawing on the vine.

Suddenly, the man noticed a plump wild strawberry on the vine. He plucked it and popped it in his mouth. It was incredibly delicious!
