If one’s treatment in Satsang is even slightly below expectation, then one talks negatively to others and discourages them.

If you listen to such talks, he would again talk about others’ faults.

But the moment you realise it, tell him clearly, “Stand up and leave. I don’t want to hear this.” Or we should leave from there.

Keep one conviction: not to listen to such talks. If you listen, you become stuck. Then you relish them.
They come with added spices.

Therefore, it’s better to get away from there.
