"It so happens that sometime the ling of Vishweshwar is removed and is again brought back according to the existences of the situation. It often happens that on account of the action of the intolerant Muslim government there may be no ling there at all. Even the circumambulation etc. should be made round the place on account of its sanctity. That is quite sufficient for the pilgrimage. As for a ceremonial bathing of the God with Mantras etc. that would not be possible."
