Mindfulness, a meditation technique in both Buddhism and Hinduism (and recommended widely in western psychological practice), is a widely misunderstood practice. It is simply the practice of "watching one's mind". "Happy", like "sad", "depressed", etc., is a feeling that comes from one's mind. Eventually, one realizes that the mind *is* the problem. (Well, the "gross" level of the "mind" is another way of putting it.) One then learns that ignoring that gross level of the mind is the next step in the process. That step results in the gross level of the mind eventually "wearing off" like mud on one's skin or silt settling in a glass of water. So, "Happy", "sad", etc., is then realized to be a part of that gross level of the mind. Mindfulness need not have all the religious or psychological trappings, but they also make people relatively happy in the meantime so perhaps the devotional techniques can be helpful. (I couldn't get into that stuff, but that's just me.) All the other stuff people do prior to learning the above is just relatively-"blind" people looking for help, which oddly is very hard to find.
