Wrong samadhi is where the mind enters calm and there's no awareness at all. ...the mind enters calm, and we don't want to come out to investigate anything. We just get stuck on that happiness ... With right samadhi, no matter what level of calm is reached, there is awareness. There is full mindfulness and clear comprehension.
