The generations of Rudra, the incarnation of anger, were so dangerous to the maintenance of universal affairs that even Brahmā, the father of the living entities, became afraid of them. The so-called devotees or followers of Rudra are also a menace. They are sometimes dangerous even to Rudra himself. Descendants of Rudra sometimes make plans to kill Rudra — by the grace of Rudra. That is the nature of his devotees.
