Wisdom is tolerance of cognitive dissonance.

The worldly person is insane from the point of view of the spiritual person.

When all is lost, when all is let go of, when all is abandoned what you are left with is an ocean of bliss. What you emerged with what you are is an ocean of bliss. Your cells and atoms and brain and bones and blood stream all of it is bliss.

If your enemy is happy, then why would they be bothered to be your enemy? Being someone's enemy is no fun. It does not add to happiness.

Actually there's a very bad trend in some cults about how Guru's are supposed to be mean to their students, and there are some who revel in this and are abusive.

You could then use the dream to learn more about yourself, others, the world, and the nature of life. You can come awake in the matrix and realize you're the one in your own dream. People on the spiritual path can do that, thus they can avoid wasting the whole night, and use it in a developmental, nice way.

The saying "no self, no problem" probably comes from Zen. In their cultures, where Buddhism is kind of taken for granted, as well as karma, causality, former and future life, and the possibility for becoming enlightened, then it's safe to skirt the danger of nihilism, which would be, I don't exist because Buddha said I have no self, and therefore I have no problem because I don't exist. That would be a bad misunderstanding. But in those cultures, it would not be as easy to have that understanding as it would be here in the west, where we really are nihilistic.
