To me groundlessness connotes something frightening. To be grounded even in groundlessness is what I aim towards. Groundlessness is a feeling of anxiety. What helps me confront such an existence and experience is accepting it and finding a space of steadfastness during the experience by way of deep breath, by allowing attention to be over some object for a time, by watching the world as if for the first time. I am more of a visual person. Seeing the benign nature of objects. The world is truly beautiful even in its changing and spiralling-out of control-nature. This Beauty found in practice of Suchness helps me to find roots even in chaos. It is denoted best in a Zen Story known as Tigers and the Strawberries.
What helps me to take it in is good stories such as The Wheel of Time presently. Apart from that, the concept of Suchness in Buddhist philosophy helps. I make it a personal training in Focus to bring my mind, as it wanders in forests of pain, back to the Pool of Suchness. Returning to The Peace of the Present Moment.
