This is like a baby sparrow being caught by a cat. To prevent a recurrence, a string is then always tightened around the cat, and it is never let go. If my mind is treated like a tied-up cat, it will not be free and will likely not be able to function as it should. If the cat is well trained, the string is untied, and it is allowed to go wherever it pleases. Then, even if the two are together, the cat will not seize the sparrow.
