Rudra to Śiva — one name across a very long road
The popular claimIn the Ṛgveda, śiva is an adjective. It took a thousand years to become the god.
The word śiva occurs in the Ṛgveda. It means kind, gracious, auspicious, and it is applied to several gods, to the winds, to a night. It is not a name. Rudra is the name, and the road from one to the other is the subject of this page.
Rudra in the Ṛgveda
Three hymns — 1.114, 2.33, 7.46 — and mentions elsewhere. He is rudra, the roarer or the red one, the etymology disputed; he is the archer whose arrows are disease and whose bow the poets ask him to keep unstrung. He is jalāṣa-bheṣaja, the one with cooling medicines — the same god who sends the fever cures it, and the hymns ask him for both restraint and remedy. He is the father of the Maruts, the storm-gods. He is braided, fierce, on the margins; the sacrifice gives him the leftovers and the north. Nobody in the Ṛgveda loves Rudra. They ask him not to harm their children, their cattle, their horses, their elders, and they mean it.
The Śatarudriya
The Yajurveda's Śatarudriya — the Namakam of the Rudram — is where the change begins. Rudra is bowed to a hundred ways, and the ways are everything: the lord of thieves, of the roads, of the fields, of the trees, of the potters and smiths, of the dogs. He is being made universal — if he is in every place and every trade, he is no longer marginal. And in the eighth anuvāka comes namaḥ śivāya ca śivatarāya ca — the adjective attached, twice, to the name. The tradition takes this as the birth of the five-syllable mantra. Historically it is the moment the word begins to stick.
The Śvetāśvatara
The Śvetāśvatara Upaniṣad, a late Upaniṣad probably of the last centuries BCE, is the first text that makes Rudra the highest — the one god, eko rudro, who stands at the end of the world; who is īśa, the Lord; who is śiva as a name and not an epithet. It is also the text from which theistic Vedānta later takes its vocabulary. After it, Śiva is a possible answer to the Upaniṣadic question. Before it, he was not.
The Purāṇas
By the Śiva, Liṅga and Skanda Purāṇas the god has everything the temple gives him: Kailāsa, Pārvatī, Gaṇeśa and Kārttikeya, the bull, the ash, the third eye, the crescent moon, the Ganges in the hair, the poison in the throat from the churning, the burning of Kāma, the destruction of Dakṣa's sacrifice — which is, in the Purāṇic telling, the old exclusion from the Vedic rite turned into a story with Śiva winning it. The dancer, Naṭarāja, is a Tamil development of the Cōḻa period, in bronze. The liṅga has its own history, argued over; the Liṅga Purāṇa's account of the pillar of fire that Brahmā and Viṣṇu could not find the ends of is the tradition's own.
Which part is from where
The bow and the arrows, the medicines, the north, the ash and the margins — Ṛgvedic Rudra. The universality and the five syllables — the Śatarudriya. The theology, the oneness, the name — the Śvetāśvatara. The family, the mountain, the stories — the Purāṇas. The dance — the Tamil south, in bronze, a thousand years after that. A worshipper standing before a liṅga with a Rudrābhiṣeka going on is standing at every one of these layers at once, and the priest is chanting the second.
The ascetic and the householder
One thread runs through all of it. Ṛgvedic Rudra is outside the village; Purāṇic Śiva is on the mountain, in the cremation ground, smeared in ash, the yogī. And yet he is the husband and the father, the god of Śivarātri and the wedding-month. The tradition never resolved this, and never wanted to: he is the god who is both, which is exactly what the Śatarudriya was doing when it bowed to him as the thief and the lord.
What this page does not say
It does not say the Rudra of the Ṛgveda and the Śiva of the temples are the same god, or that they are different ones — the tradition says the first, and the history shows the road. It lays out the road. A reader who knows the temple Śiva now knows where each thing they see came from, and how long the word śiva took to become his name.
