The amazing wheel

In our body the power which manifest the soul , call Vaak वाक् By this vaak soul manifest thousands of akshara (the desires).So Vaak is called Sahsraksra सहस्राक्षरा This body where the soul is residing actually its नेमि  boundry or felloe or circumference. In the Atharva Veda in  a mantra beautifully saying about a wheel.......................एकं चक्रं वर्तत एक नेमि ,सहस्राक्षरम प्र पुरो नि पश्चा ।अर्धेन विश्वं भुवनं जजान ,यद् अस्यार्ध क्व तद बभुवं ।। 
This wheel goes further पुरः and also goes back पश्चा Here we can see our soul has some time futuristic nature ,always imagines about the coming time.Some time it goes in back memories .That is why this wheel runs ahead and back also.Now in second pera mantra says 'Ardhen vishvam bhuvanam jajaan'अर्धेन विश्वं भुवनं जजान From this half it makes the whole world of man.Here inner world of man which has been made by the Kosas through which it manifests.Manomaya,pranmaya and annamaya.This is half in totality.This is not full wheel.The man take birth with this half wheel.The un-manifested world is other half.The Mantra says यद् अस्यार्ध क्व तद बभुवं its half part what happened.What happened from its half.....!
