Nice mixture of techniques you have out there. Although I'm not convinced they're effective when mixed up in real time, like noting and your micro-happiness practice. E.g., if you drive yourself to enjoy this moment rather than dispassionately noting it, that's also something you can note. I think a technique is effective when you commit totally to it for a set period of time (15 minutes, 2 years, whatever)
Jhana is a very overloaded word. It can mean many things:
- Visuddhimagga absorption (total, can't do insight from within it)
- A softer samadhi altered state from which you can do insight (Gunaratana seems to use this definition)
- A bunch of vipassana ñanas put together (many authors seem to implicitly use this one)
- The stability of concentration that enables you to do vipassana, without implying it's an altered state of consciousness
...so it's a very slippery business trying to read texts and make changes to one's own practice based on an author's opinion on something called jhana. I think they are a good support, but the personal experience of vipassana with varying degrees of absorption and momentary concentration is far superior.
