You are not talking on phone but are receiving the sounds through the powers of the Sadhana. Just imagine that you are sitting in Delhi and are talking to your wife who is in Bombay.
Through the power of his Sadhana, Sanjay was able to see the battle of Mahabharat going on in Kurukshetra and narrate the events to Dhritrashtra, while he sat in the palace in Hastinapur (Delhi). Dhritrashtra, the father of Kauravs was keen to know about the goings-on in the battle and as he was blind he could only hear about the proceedings.
or radio? In Mahabharat era, Sanjay had accomplished Divya Drishti Sadhana ,Door Shravan or Divya Shravan Sadhana through which he could visualise events occurring hundreds of miles away. Do you wish to attain the power to talk to people sitting thousand of miles away from you, without the help of any scientific equipment? * Do you wish you were able to read the thoughts of others? * Do you wish you were able to know about events occurring thousands of miles away without having to switch on a T.V.
