Buddha said that someone who brushes against you in the street does this as a result of sharing karma with you for five hundred lifetimes. So our ... practicing, eating, and living together mean that we have met and continued to meet for many, many lifetimes — strong karma together. And this will not stop in the future. We will meet again and again, into infinite time.
