Even is someone is trolling your Discord server, you should train like this: ‘My mind will not degenerate. I will blurt out no bad words. I will remain full of sympathy, with a heart of love and no secret hate. And with them as a basis, we will meditate spreading a heart like the earth to everyone in the world—abundant, expansive, limitless, free of enmity and ill will.’ That’s how you should train.
