Balance

Despite the emphasis on developing the five faculties first, Sayadaw goes on to explain how they need balance.

1. Faith can produce too much emotion that gets in the way
2. Too much effort and the mind is restless
3. Excessive concentration produces laziness
4. Too much wisdom and a yogi ends up just discussing anapanasati ad nauseum (oh I've been witness to that)....

I did not see a warning about too much mindfulness here.......
