Council of nine :Focus your mind and emotions only on the positive.

[Asolsutsesvyl]

The quote (I won't check the link, as I no longer use Facebook) reminds me of a simple metaphor for such "positive psychology". Alcohol. Restricting consciousness to only what feels positive is very much like what people often get drunk in order to accomplish. Sometimes, psychology is used to do the same thing. Some types of New Age teaching combine that with great visions of unity and playing a positive part in creation.

Agua put a finer point to a healthy alternative than I can formulate. But I'm reminded of something related, a Carl Jung quote: "People do not become enlightened by imagining figures of light, but by making the darkness conscious."
