Body ages, you don’t age. You are the knower of the false notion of body ageing or body dying. Let me know who else other than your deep contemplation can gift you this *awakening*? Intellectual understanding is only a pointer. Practice of meditation is the process, *awakening* is natural outcome out of Grace of Mother Divine who unveils this secret to Her child. Now you are free from the fear of death and uncertainty. 
Prostrations to Sages of Bharat!
