When we are young and without a language we are living in the NOW. We do not think or argue with ourselves. We just are.
When we learn to speak we learn to think and to argue with ourselves. We discuss with us in our mind or with others. We think and rethink and overthink, again and again.
We need to unlearn our language and symbolism in order to free our mind and our doing from the binding thoughts. We have to clear our thoughts and undo the thinking about it. Only then we will be able to be in the now. To live the moment and just be.
