Hindu sacred writings like Vishnu Purana, Matsya Purana, and Bhagavad Gita utilize the word Rudra to coin the eleven types of Shiva (Ekadasha-Rudras) born to end the savagery and oppression of rakshasas on the planet and paradise. Various sacred texts have different histories of these Rudra Avatars of Lord Shiva.
In the Svetasvatara Upanishad is a phrase
"Eko hi rudro na dvitiya tasthur" meaning Rudra is truly one and there is no place for a second. Mahadev - Shiv, both infinitely kind and terrifyingly destructive , created 11 immortal beings: Kapali, Pingala, Bhima, Virupaksa, Vilohita, Ajesha, Shasana, Shasta, Shambhu, Chanda, and Dhruva, which came to be known as the mighty 11 Rudras.
It is said that this concept subsequently became the basis for advaita school of thought. This Upanishad describes Rudra as the very Brahman and the Highest Reality and declaration of Truth. Thus the Purusha That controls Maya which is but Prakriti of the Samkhya as identified in the Upanishad is without doubt, Lord Siva. Svetasvatara Upanishad reflects the maturity and spirit of Saivism during vedic times.
Svetasvatara Upanishad 3.2: Siva rules (isata) these worlds with His enormous powers (isanibhi). He stands apart from all creatures (pratyan janan) and He is the protector of all the worlds (visvabhuvana gopa). At the end of creation He withdraws these worlds.
Svetasvatara Upanishad 3.4: He is the source and origin of all gods, the ruler of them and as Iswara gives birth to Hiranyagarbha, the golden germ.
Svetasvatara Upanishad 3.8: White in color (aditya varnam), beyond darkness and ignorance (tamasa parastat), He alone can take us beyond the cycle of births and deaths. There is no other path that can help us.
Svetasvatara Upanishad 3.9: There is nothing else that is higher or smaller than Him. He alone pervades the whole universe.
Svetasvatara Upanishad 3.11: "Sa bhagavan tasmat sarva-gatas sivah." He is the Lord and He, Siva, is therefore found everywhere. This is when Lord Shiva releases the destructive energies to dismantle all of the creation by performing a cosmic dance known as Shiva Tandav.
This form of Shiva as a cosmic dancer is known as Nataraja. Some of his avatars are related to protecting his devotees from the devils and proud Gods as well. While there are 19 different avatars of Shiva, however, ‘Nataraja’ is not an avatar but Lord Shiva himself as the divine dancer.
Nataraja is Shiva during the apocalypse dances called the cosmic dance of Shiva “tandav” symbolizing the interplay of dynamic and static divine energy flow, which contains five principles of eternal energy- creation, preservation, destruction, illusion, and emancipation. However, five avatars of all his incarnations are hideously important as well as assumed to be the most valuable and effective for his devotees. The most important five incarnations are: Tatpurush, Namadeva, Aghoresh, Sadhojat and Ishan.
Tatpurush; is the most popular third incarnation of the Lord Shiva which was manifested in the 21st Kalpa of the planet known as Peetavasa. It was appeared by the prayer of the Lord Brahma.
Naamdeva; During the 20th Kalpa known as the Rakta, Lord Brahma got his complexion changed to a red. Another entity was appeared from him of the red complexion, which was name by him as a Namadeva. It is considered as the Naamdeva was also the incarnation of Lord Shiva.
Aghoresh; In the Shiva Kalpa (after the Peetavasa Kalp), an entity of black color complexion was appeared by the Lord Brahma when he was in deep meditation state. Lord Brahma named that entity as Aghor Shiva and considered as another form of Lord Shiva.
Sadhojat; During the 19th Kalpa known as Shweta Lohit, there appeared an entity by the Lord Brahma while he was meditating, which was named by him as Sadhojat. It is considered that this form of the Lord Shiva was the first incarnation. Four disciples of the Sadhojat were appeared by his own body named Nandan, Vishwanandan, Sunand and Upanandan.
Ishan; In the Vishwaroop Kalpa, Ishan form of the Lord Shiva and Saraswati were manifested. Four divine entities like Mundi, Shikhandi, Caste and Ardhamundi were manifested from the Ishan Shiva. Lord Brahma was blessed by all of them for the creation facility.
As science states ‘energy can neither be created nor destroyed, the destruction initiated by Shiva with his cosmic dance is a medium for recreation and the cycle never ends. His cosmic dance in an aureole of fire, causing wild thunderstorms all around the world, and not only the earth is affected, but also the Sun, the Moon, and the stellar bodies with his matted hair, marks of ash on forehead, the damaru, and trident. He lifts his left leg balancing the right above a demon of ignorance. This cosmic dance of Shiva is best described in the popular Shiva Tandav Stotram composed by Ravana.
There are eight idols of the Lord Shiva which includes Ugra, Sharva, Bhava, Rudra, Bheema, Pashupati, Ishan and Mahadeva. Ten fastidious incarnations of the God Shiva known as Dash Avatar and 10 incarnations of the Mata Sakti known as the Dash Mahavidya. Describing concerning to the 10 incarnations and their corresponding power (Shakti), the first incarnation of Lord Shiva was the Mahakal and Shakti was Mahakali. Second incarnation of both of them was Tar and Tara. Third incarnation of both of them was Bhuvaneshwar and Bhuvaneshwari. Fourth incarnation was Shodash and Shodashi or Shri. Fifth incarnation was Bhairav and Bhairavi. The sixth incarnation was Chhinamastak and Chhinamasta. Seventh incarnation was Dhoomvan and Dhoomvati. The eighth incarnation was Baglamukh and Baglamukhi. The ninth incarnation was Matang and Matangi. Tenth incarnation was Kamal and Kamala.
Lord Shiva took birth on the earth as the eleven Rudras from the Kashyap wife’s (Surabhi) womb. These forms of the eleven Rudras are associated with the battles with demons in the past in order to save the people and Gods. Following are the name of eleven Rudras:
1) Kapali 2) Pingal 3) Bheem 4) Virupaksha 5) Vilohit 6) Shastra 7) Ajapaad 8) Ahirbudhnya 9) Shambhu 10) Chand and 11) Bhav. These 11 Rudra Avatars of Lord Shiva, came into existence to protect divine beings and were gifted in battle. They obliterated the rakshasa and once again gave Indra, his rightful throne, as the legitimate King of the Gods and the city of Amrawati Puri since the time was forever made the city to shield it from such rakshasas and help the divine beings in their battle against evil.
To succor the law and equilibrium of nature, there were several different Avatars of Lord Shiva in different Yugas. Kurma Purana discusses 28 Lord Shiva Avatars, yet in Shiva Purana, 19 Incarnations of Lord Shiva;
Piplaad Avatar; Lord Shiva was born to Rishi Dadhichi and his wife Swarcha as Piplaad. However, the sage and his wife soon lost their lives because of Shani's position in the sky at the time of his birth. Thus, Piplaad sought revenge on Shani and was the reason behind the planet's fall from its divine home. Afterward, he pardoned Shani, when the Devas intervened, on the prerequisite that the planet could never cause trouble for anyone before it turns 16 years old. Thus, revering the Piplaad avatar of Lord Shiva assists with disposing of Shani dosha.
