Yes, All thoughts are concepts. They need to die. When the thoughts are weak, the Brahma Astra of Bhagavan should be used to whom are these thoughts, me, who am I. Then there is silence. Till the next thought. The battle goes on, guided by our real nature-or Arunachala or Bhagawan- till there is finally no thought. Silence reigns, peace reigns. All beings born and yet to be born will take this journey. But is there a journey.? Are we always that? Then what about the world around us.? Our pain, trials and tribulations. Is it all a mono act play ,enacted by us out of delusion, till it persists?
