Some people seem to think that. But a chain letter asks you to send copies of it on to others. That’s not what this is asking. These people miss the clear statement that it is a detailed meditation practice that exists in a certain Buddhist text — the Surangama Sutra — that they should help publicize because that practice helps you to protect yourself during traumatic events. It’s more like the Red Cross and their offered classes to teach people how to help others who are injured in certain ways.
