When He says “Shivatvamasi” He means it. “You are Shiva” If you listen to his truth and declare Shivoham! I am Shiva! He will not feel threatened, he will not judge you, he will not question you, he will not be asking, how dare you declare, you are Shiva, have you qualified yourself, how you done all the tapas, have you purified yourself, no! don’t worry, the moment you declare, He is so happy, he has a one more being through which He can manifest Himself.
