What can we do for people who are very confused or even suffer from psychoses?

Lama Ole’s answer:

In a case like that, I would work with mantras. Give them the good, sturdy om mani peme hung mantra, and get them used to saying it. A mantra works like a protective oil film. Disturbances usually make scratches on our mind, creating habits that we fall into again and again. But when we use a mantra, the disturbances slide back and forth and then fall away without creating habits. A good dose of om mani peme hung for everybody would be good. You just have to watch out that they don’t think you are trying to convert them by force.
