We have not lost anything. God is not lost and hence has not to be found. We have only forgotten; it is just a question of remembrance. It is there in the deepest core of our being. Call it truth, God , bliss, beauty: all those things indicate the same phenomenon. There is something eternal in our beings, Something immortal, something divine.
All that we have to do is to go deep, dive deep, into our own being, and to see, realize, recognize. Hence the journey is not really a journey. We are not to go anywhere; we have simply to sit silently and be.
