Aadieshwar

His name means The Auspicious One. He is Pure Consciousness, Chidanandaroopa - the form of joy that pure consciousness takes. He is the oldest god known to mankind, and more interestingly is perhaps the oldest living god, tracing a genealogy of worship that is easily five thousand years old. Naturally, therefore, he is described as the God with no lineage. Like Yahweh, who may be his only contemporary, his name was not to be taken in vain. In fact his name was not to be uttered at all. He is the howler, Rudra, when he first appears to us in the Rig Veda. He is Raudra Brahman, the wild God of the Hymns. He is also Nataraja, the elegant King of the Dance, and in fact of all the fine arts. He is the Lord of yoga, the culmination of the universe, the cause of its dissolution - yet always transcending such petty events.
To attempt an overview of Shiva in one essay is an act of extreme idiocy. I shall therefore seek to communicate some of the flavors that are associated with Shiva, trusting that time will be vouchsafed us to explore him in detail as we grow as a web-site. Shiva has been around for so long that entire encyclopedias on him are necessary to get just a bird's eye view. This god is perhaps the single most important influence on the arts and culture of the Indian subcontinent. In a very real sense, you find Shiva all over the country, he is in fact the country, so closely interwoven are the myths of his actions with the culture and geography of the land. So strong is Shiva's hold on the imagination that all local area gods which seek to gain in prestige, or are sought to be subverted to the main body of the Hindu religion, end up being described as various manifestations of Shiva. If the god lives on a hill, a forest or a cave then there is no way he escapes being but one more aspect of Mahadeva - the great god who loves to linger in hills, forests and caves. This is what has happened to Khandoba in Maharashtra, Skanda in Tamil Nadu and Ayyapan in Kerala to give the three most common examples. In fact another manner of accommodating these local religions was to decree the gods to be sons of Shiva.
The Rig Vedic Shiva was known as Rudra. He was a grim mysterious god, living on the fringes of Vedic society, a god who was so much of an outsider that he was not even entitled to a share in the fire sacrifices. Yet the Vedic pantheon was clearly in awe of this self sufficient Hunter-God. The hymns praise him in all-too-visible anxiety that his strange powers may be aroused, and his name as mentioned was never to be invoked. "We live in dread, and pray that you pass us by", quavers the Rig Vedic verse. Yet it immediately goes on to add that He is the Awakener, who when touched by pleas, grants a thousand kinds of balm that heal.
In a sense Rudra was too much a part of the Life-Force, too acutely felt to be just a god. Rudra punishes Prajapati for the first primordial act of incest and in a sense he is the defender of Dharma ever since. He is also a slayer of a brahmana, Prajapati, in the service of a higher morality, a fact that has caused much anguish to medieval commentators who were busy trying to show brahmanas were gods on earth as well as in heaven. Rudra-Shiva is thus always about living an authentic life, with utter disdain for convention.
This Vedic manifestation of Shiva was thought to be the earliest known(1500 B.C.) before he became the great God of later Hinduism. Then came the discovery of a few seals from the Harrapan civilization (2750 B.C.) and the picture changed completely. The seals show a figure who is so manifestly Shiva that it had to be acknowledged as such, even though it smashed the nice theory that was emerging of invading Aryans destroying the cities of the Indus valley. It is known as the proto-Shiva seal. However, for those who can read the signs and can decode the evidence, this figure is far more important.
He is surrounded by animals, which directly links him up with the Rudra-Pashupatinatha of the Vedas. The tiger, the elephant, and the bull depicted here, all play prominent parts in the Shiva mythology. Even more importantly he is shown in a typical yogic posture, which would indicate the knowledge of the ancient art.
This posture is the Udharva Linga posture (and not the ithyphallic posture as is so easily assumed) and it indicates the triumph over the sexual impulse.. The balls of the feet press into the sacral region behind and beneath the testicles as is shown. The lingam is erect and it presses into the navel, signifying the complete conquest of the sexual energy. He is now Udharva Retas, "he whose semen flows upwards". In the yogic system when you do not dissipate semen through ejaculation, it transforms itself into a food for the brain called ojas, vital energy, and is the source of the creative force that alone can provide you with the fuel to break through into enlightenment. This posture is commonly practiced even today and the udharva linga experience is not uncommon for many spiritual practitioners. Even the founder of Kriya yoga has left an account of precisely this linga entering the navel and the subsequent freedom from all thoughts and desire of lust.
Inevitably, Shiva the Conqueror of Lust and Desire is also known as the erotic ascetic! The Tantrik tradition uses the Shiva Energy very heavily and many of the texts of Tantra are lectures that Shiva gives to his spouse who may be Kali or Parvati, but actually is a representative of all the Divine Feminine energy in the world.
Shiva's sexuality inevitably brings us to the Shiva lingam, the supposedly sacred phallus. Contrary to popular perception, the Shiva lingam has a world of meaning attached to it and it is not just the obvious one of phallic symbolism. Most lingams are representations of Shiva who is never worshipped in the form of an image. Popular mythology holds that he was cursed so by an enraged rishi. The lingam is an abstract stand-in for the Howler who must never be named. The entire process is an elaborate avoidance of naming the dread name by substituting something else, which is also a creative and generative force.
Under Tantrik influence, the lingam placed in a yoni base - which means exactly what it sounds like - became a frank avowal of the ultimate origin of new life, it was fertility symbolism at its best. Educated Hindus tend to be over-apologetic about this aspect, though the average Hindu lives in a curious innocence about the nature of the Lingam. This was typically expressed in Gandhi's naïve confession that he had to read foreign authors before he realized that there might be anything sexual about the lingam.
According to Swami Vivekananda, not just the lingam but also the entire external image of Shiva is an elaborate symbolical construct. In his view, Shiva is a personification of the entire Vedic fire sacrifice. Thus the ash with which his body is smeared is the ash of the sacrifice. (Ash is also what's left when everything is destroyed and it does not decay. So too with god, what is left when everything is gone. Shiva covers himself with ash because he is the only life form in the Universe who is aware of this truth at every moment.) The white complexion of Shiva is indicative of the smoke of the sacrifice. The animals He is associated with indicate the animals tied to the sacrificial posts and so on. The Shiva linga, in Vivekananda's view is actually a feebly recalled Yupa Stambha, the Cosmic Pillar that is the center and support of the Universe, The Axis Mundi, in fact. This yupa stambha is always represented in all fire sacrifices and it is permanently installed in temples in the form of the linga.
If prayers could not be offered to images of Shiva, then the temples could be covered with depictions of scenes from his ancient life. So great was the Shiva factor in Indian art forms that it almost obscures the other gods. The temples and their sculptures run riot. Khajuraho, Ellora, Elephanta, Rameshwaram, the Chola temples, the Bhuvaneshwar and Madhya Pradesh temples, and the great dancing Shiva temple at Chidambaram, it's a universe drunk on the creative energy, fertile and fecund with originality and beauty that is not as well regarded as it should be, merely because there is too much of it. If there were only one such temple in India the world would have gone mad with appreciation. As such, you can actually overdose on beauty, the Beauty that is the transcendent state of the Truth that is Shiva, expressed in the famous formulation Satyam, Shivam, Sundaram.
The mythologies surrounding Shiva are immense. It must be remembered that the Shiva story has been going on for five thousand years now and they only too obviously reflect the concerns of people at the time they were being composed. Shiva Himself is a composite god today, involving many local area gods and little tradition mythologies into his all-embracing grasp. Shiva is more or less what you want Him to be, as in Him all contradictions casually coexist. The notion of Shiva as exclusively a Wild Man of the forests and mountains, traveling with a band of ghosts and ghouls as their leader, Bhoothnath, is a recent phase of his worship. For while He was always capable of peculiar behavior, Shiva used to live outside of society not because He had rejected it but because He had transcended it. Shiva is repeatedly described as the Supreme Master of all the Arts, and that indicates a highly socialized being, the Nagarika of ancient India, not a rustic.
To those who did not understand this aspect of the lord, to those who still had on their defensive shell of sophistication and cynicism, Shiva was Bholenath, the Simpleton God. Yet, traditionally India has regarded Shiva not as any of these roles but as Vishwanatha - the Lord of the Universe. That is why in all the old temples you find him represented as a king, decked out in lordly robes with crowns and jewels. This homeless-wanderer recent incarnation of Shiva was perhaps a reflection of a culture that had lost its moorings and was reeling under alien domination.
Yet even at this much reduced level, Shiva seems to appeal the most powerfully, of all the gods of India, to the collective unconscious. Since most Goddess worshipers also acknowledge Him as the divine spouse of the Goddess, Shiva may easily have the most devotes in sheer number alone. He is laughed at as an old man by devotees with the affection that comes only with comfort. Yet in some corner of the old limbic brain he lurks, Rudra-Shiva, the old god of India, the source of the songs of the Rig Veda.

"Of all who are born You are the greatest Of all the powers, you are the most compellingLustre itself becomes pale and outshone by you O Rudra!Protect us from the hordes of sins that assault us Stand between us and them Repel them with the thunderbolt of your arm O Rudra! Lead us to the other bank Let us cross with ease."
