Why God is called Hara by wise people

शरभावतारवर्णनं नाम द्वादशोऽध्यायः

Sharabha incarnation description Chapter 12

देवा उचुः |

Devas said (to Lord Shiva in the form of Sharabha incarnation)

यतो हरसि संसारं हर इत्युच्यते बुधैः | 26

Since you take away (destroy) the material world, wise people call you Hara.
