Upanishads say that he who says he knows, knows not and he who says he doesn't know knows something. The meaning is that the reality cannot be grasped by the senses and if somebody says that he doesn't know it, he at least has come to a state in which he has understood the limitations of the senses. This takes him on a journey of self discovery in which he goes to his core.
He negates all the manifested things through the process of 'neti neti' ( not this, not this) and ultimately reaches the pure consciousness which is the ever existing reality. Bhagavan Ramana Maharshi said that we should abide in that Self and that was jnana. In that state only the Self exists.
Isavasyopanishad says he who sees himself in others and others in him has no sorrow, worry or trouble. He sees only the Self. There is nothing other than the self.
I had a discussion with Dr. Sachin of TISA (The Indian Stammering Association) recently. I knew that he also read Bhagavan Ramana Maharshi a lot and slowly the discussion went into the Bhagavan and Indian philosophy. When it came to the point of abiding in the Self, he told initially he was not sure whether to abide in the stammering self or his non stammering self. Later on he realised that the Self was beyond all these.
When we came to the point of discussing the concept of 'he who says he knows, knows not', he told if a person says he is a stammerer he is wrong; if he says he is a non stammerer, again he is wrong. He is beyond all these.
Yes we are beyond all these concepts. The real recovery from stammering happens when we understand this reality. It doesn't happen through any technique. All the techniques like bouncing, prolongation etc should be discarded at one point; to borrow the words of the Maharshi once again, like the stick used for stirring the fire getting burnt in the end.
As Sri M, the great yogi of our time, says in his talks and in his writings, one of the sparks for anybody to go along the path of Self discovery is depression or sorrow. This is corroborated by the fact that the first chapter of Bhagavat Gita is known as Arjuna Vishada Yoga.
So let's consider the stammering as the necessary spark for us to go on the path of Self discovery and achieve the real recovery. In that state where only the Self exists, is there anything called stammering self or non stammering self?
