Lord Shiva: Worshipping Lord Shiva

                                                                  Q. Is it forbidden to perform parikrama of Lord Shiva?

                                                                  By parikrama I assume you mean circumambulation. Scriptures say that Lord Siva is half circumambulated. You may notice that in Siva temples there is often a fence on one side. When circumambulating Lord Siva we go around to the fence, and then turn around and go back. This is called half circumambulation.

                                                                  Q. 1. Lord Krishna told Arjuna: "Those who claim to be directly My devotees are actually not my devotees. But those who are devotees of my servants are factually My devotees." In Srimad Bhagavatam purports of first canto, Srila Prabhupada mentions that Lord Shiva is a pure devotee of Lord Krishna. According to the above sloka, does it not directly imply that all of us must serve Lord Shiva? How far is this justifiable?

                                                                  Q. In addressing persons who are worshipers of Lord Siva, we find them sometimes quoting Ramayana as one proof that Siva is supreme. They refer to the lila of Ram's worshiping Siva before going to Lanka. How to best respond to this line of reasoning?
