Mindfulness has been a useful stepping stone in my awakening process. I had a practice of moving my attention away from thought and into "the present moment" - this is usually called being present or mindful. I adhered to this practice fiercely for almost a year and it seemed to produce profound results. I would shift my attention away from thought and onto any sensation or perception. This is objective meditation - it is objective because we use sensation and perception to place our attention on an object, mainly our physical body. I would do this practice constantly, not only when in sitting meditation.
