In plain words
This feeling of compassion must rise in every man. Grief must never come to man. When does grief come? Only when we nurture bad qualities does the feeling of grief come into us.

But the birds that come do not keep quiet. They make a noise. Not only that. If anyone comes to rest under that tree, they foul the whole place. That is why the revered Śaṅkara
