Swami Vishwar Upananda passed away in Kashi Sivashram. Switanji said it was just like a clock you know the hands of a clock move and when it runs out of it's winding up in. He felt something is wrong and he quickly put the spoon down and rushed to the doctor who was still walking across the courtyard. The doctor came back to see Swami had passed away.
