(Spirit Rock Meditation Center) After some brief initial instructions in posture, setting intentions, cultivating stability of mind, and basic mindfulness, there is a period of settling, followed by brief instructions on being mindful of any moments of reactivity, and then, some time later, on being mindful of any moderate or greater (while still workable) moments of pleasant or unpleasant experiences, noticing any tendencies to move from pleasant to craving and grasping (one form of reactivity), and to move from unpleasant to not wanting to pushing away in some way (the other main form of reactivity).
