Question: What happens if wrong thoughts enter into your mind during meditation?

Sri Chinmoy: The moment a thought enters into your mind, especially any undivine thought or wrong thought, your aspiration must cut it to pieces, because during meditation everything is very intense. While you are talking or engaging in your ordinary earthly activities you can have any kind of thought, for your thoughts are not intense at those times. But during your meditation, if any undivine thought comes, the power of your meditation enlarges and intensifies it, and it ruins part of your subtle and spiritual being. If a good thought comes, you can try to enlarge it as much as possible. If the good thoughts are on a lower level, try to lift them up to a higher level. But if you have a bad thought, just cut it off, kill it.
