"This is a slow ordinary walk based on the awareness of the feet touching the ground. You can walk in a circle or a line of 10 to 15 steps going back and forth, inside or out of doors. Eyes should be lowered on the ground a few steps ahead. While walking, the attention should go to the contact of each foot as it touches the ground. If other things arise, stop paying attention to your feet, notice whatever else took your attention and then return to your feet.
It is the same technique as is sitting - but watching a different primary object. You can walk for 20-30 minutes. " ~Osho
