Zen Steady allows you to increase your concentration and steadiness. During your meditation, start Zen Steady, tap on the black stone then place the device on the palm of your hand facing up in fron of you. Your objective is to keep your hand as straight as possible for as long as you can, to keep the stone inside the circles. If the stone falls out you have to start again. Keep your eyes on the stone to increase concentration, whether youre a beginner or a master of zen meditation.
