SHIVA __ RUDRA

Shiva as Rudra (and Rudravtars) - Rudra means "angry" and as Shiva is Bholenath, Shiva also represents the primodeal rage. So, the Rudra aspect of Shiva can be seen as the exact opposite of Bholenath aspect of Shiva. Rudra can be seen as the pure fierceness, rage and destrutive nature of the universe and probably that's what makes Shiva so fearsome too. Apart from doomsday and Tandav ntratya though, some aspects of the Rudra have incarnated periodically. There have been ten rudra avatars but the most notable Rudra avatar is Hanuman. It can be observed as Shiva's Rudra incarnation and Vishnu's incarnations represent the same duality as observed in other Hindu philosophies.
