Lord Shiva is one of the trinity God and Rudra is the Vedic God who has several features like Lord Shiva. In many Hindu traditions and texts, these two Lords share the same personality. In more general sense, Lord Rudra represents as a destructive and fierce deity and is regarded as the god of the roaring storm.
In the present generation of Hinduism, Lord Shiva is addressed as Lord Rudra. It is to be noted that in Rig Veda 2.33, Lord Shiva is cited as the “Father of the Rudras” that means a group of storm gods. On the other hand, Rudram is one of the most holy hymns of Hinduism found both in the Yajur Vedas and in the Rig Vedas. As an epithet for Mitra, Agni and Indra many times the term Shiva is also used. It is to be remembered that the older god Rudra is not universally accepted as the identification of Lord Shiva.
The Rudra is known as “The Archer” therefore an essential attribute of Rudra is the arrow. In the Shiva Sahasranama, this particular name appears several times. It is to be noted that the word “Rudra” is directly derived from the Sanskrit language which means to Kill or to injure. Therefore the word “Rudra” largely means “One who can kill the forces of darkness”. The Lord is also locally known as Bramahasta that means “Armed with arrows in his hands”. The words direct meaning is “Archer”.
