When we come to the table, we shouldn't negotiate right away. We should spend time walking together, eating together, making acquaintance, telling each other about our own suffering, without blame or condemnation. It takes maybe one, two, three weeks to do that. And if communication and understanding are possible, negotiation will be easier. So if I am to organize a peace negotiation, I will organize it in that way.
Loneliness cannot be alleviated just by the coming together of two bodies, unless there is also good communication, understanding, and loving kindness.
You can practice deep listening in order to relieve the suffering in us, and in the other person. That kind of listening is described as compassionate listening. You listen only for the purpose of relieving suffering in the other person.
If you're a politician, you might want to learn the Buddhist way of negotiation. Restoring communication and bringing back reconciliation is clear and concrete in Buddhism.
