One of the first exercise we teach the kids in our class is mindful listening. We start with the simple act of sitting in the right posture, closing their eyes to reflect willingness and intent. We then chime a bell and invite children to listen to the bell through the whole sound of the bell. They have to listen to the bell through the whole process of chiming: the moment the bell rings till the moment it ends. End as defined: No trace of any sound (Absolute stillness). They are to raise their hands once the sound is completely gone.
Its interesting to watch the stillness in the room, the quiet and the peace that envelopes with all the kids in the room focused on one object. There is something magical about human beings being still and focusing on one thing.
