Shiva's form:
Shiva has a Trident in the right lower arm, with a crescent moon on his head. He is said to be fair like camphor or like an ice clad mountain. He has fire and Damaru and Mala or a kind of weapon. He wears five serpents as ornaments. He wears a garland of skulls. He is pressing with his feet the demon Muyalaka, a dwarf holding a cobra. He faces south. Panchakshara itself is his body. It is believed that Shiva became a god through meditating everyday.
Third eye:
Shiva is often depicted with a third eye, with which he burned Desire (Kāma) to ashes, called "Tryambakam" (Sanskrit: त्र्यम्बकम्), which occurs in many scriptural sources. In classical Sanskrit, the word ambaka denotes "an eye", and in the Mahabharata, Shiva is depicted as three-eyed, so this name is sometimes translated as "having three eyes". However, in Vedic Sanskrit, the word ambā or ambikā means "mother", and this early meaning of the word is the basis for the translation "three mothers". These three mother-goddesses who are collectively called the Ambikās. Other related translations have been based on the idea that the name actually refers to the oblations given to Rudra, which according to some traditions were shared with the goddess Ambikā.
Crescent moon:
Shiva bears on his head the crescent moon.[70] The epithet Chandraśekhara (Sanskrit: चन्द्रशेखर "Having the moon as his crest" - chandra = "moon"; śekhara = "crest, crown")refers to this feature. The placement of the moon on his head as a standard iconographic feature dates to the period when Rudra rose to prominence and became the major deity Rudra-Shiva.The origin of this linkage may be due to the identification of the moon with Soma, and there is a hymn in the Rig Veda where Soma and Rudra are jointly implored, and in later literature, Soma and Rudra came to be identified with one another, as were Soma and the moon.The crescent moon is shown on the side of the Lord's head as an ornament. The waxing and waning phenomenon of the moon symbolizes the time cycle through which creation evolves from the beginning to the end. Since the Lord is the Eternal Reality, He is beyond time. Thus, the crescent moon is only one of His ornaments. The wearing of the crescent moon in his head indicates that He has controlled the mind perfectly.
Ashes:
Shiva smears his body with ashes (bhasma).Some forms of Shiva, such as Bhairava, are associated with a very old Indian tradition of cremation-ground asceticism that was practiced by some groups who were outside the fold of brahmanic orthodoxy.These practices associated with cremation grounds are also mentioned in the Pali canon of Theravada Buddhism.One epithet for Shiva is "inhabitant of the cremation ground" (Sanskrit: śmaśānavāsin, also spelled Shmashanavasin), referring to this connection.
Matted hair:
Shiva's distinctive hair style is noted in the epithets Jaṭin, "the one with matted hair",and Kapardin, "endowed with matted hair"or "wearing his hair wound in a braid in a shell-like (kaparda) fashion".A kaparda is a cowrie shell, or a braid of hair in the form of a shell, or, more generally, hair that is shaggy or curly. His hair is said to be like molten gold in color or being yellowish-white.
Blue throat:
The epithet Nīlakaṇtha (Sanskrit नीलकण्ठ; nīla = "blue", kaṇtha = "throat") refers to a story in which Shiva drank the poison churned up from the world ocean. (See Halāhala.)
Halahala
Halāhala (Hindi हलाहल) or Kalakootam (Sanskrit कालकूटं ) is the name of a poison (as per Hindu mythology) created from the sea when Devas (Gods) and Asuras (Demons) churned the sea (see Samudra manthan ) in order to obtain Amrita, the nectar of immortality.
Fourteen different ratnas (gems) were recovered in this exercise, mostly retained by the Gods after the Demons tried to cheat them. But before Amrita could be recovered, Halāhala ("the most vicious and venomous poison of universe") was produced, which started killing both sides. As no one could bear the poisonous fumes emitted by the poison, both Devas and Asuras began to collapse due to asphyxiation. They ran for help to Brahma, who looked to Vishnu for advice. Vishnu said that only Shiva could digest the deadly poison. So both parties went to Kailasha and prayed to Lord Shiva for help. Shiva chose to consume the poison and thus drank it. His wife Parvati, alarmed, stopped it in his throat with her hands, thus earning him the name Viṣakaṇṭha (the one who held poison in his throat). The poison made his throat turn blue; hence, he is also known as Nīlakaṇṭha (the one with a blue throat).
Gosaikunda lake is believed to have formed from the digging of the land by the Trishul (holy three-pointed spear, similar to the western trident) of lord Shiva. As after he drank the poison, he desperately wanted cold water to quench the thirst generated due to overwhelming heat of the poison.

Sacred Ganges:
The Ganges river flows from the matted hair of Shiva. The epithet Gaṅgādhara ("bearer of the river Gaṅgā") refers to this feature. The Gaṅgā (Ganges), one of the major rivers of the country, is said to have made her abode in Shiva's hair. The flow of the Ganges also represents the nectar of immortality.
Tiger skin:
He is often shown seated upon a tiger skin,an honour reserved for the most accomplished of Hindu ascetics, the Brahmarishis.Tiger represents lust. His sitting on the tiger’s skin indicates that He has conquered lust.
Serpents:
Shiva is often shown garlanded with a snake.His wearing of serpents on the neck denotes wisdom and eternity.
Deer:
His holding deer on one hand indicates that He has removed the Chanchalata (tossing) of the mind. Deer jumps from one place to another swiftly. The mind also jumps from one object to another.
Trident:
(Sanskrit: Trishula): Shiva's particular weapon is the trident.His Trisul that is held in His right hand represents the three Gunas—Sattva, Rajas and Tamas. That is the emblem of sovereignty. He rules the world through these three Gunas. The Damaru in His left hand represents the Sabda Brahman. It represents OM from which all languages are formed. It is He who formed the Sanskrit language out of the Damaru sound.
Drum:
A small drum shaped like an hourglass is known as a damaru (Sanskrit: ḍamaru).This is one of the attributes of Shiva in his famous dancing representationknown as Nataraja. A specific hand gesture (mudra) called ḍamaru-hasta (Sanskrit for "ḍamaru-hand") is used to hold the drum.This drum is particularly used as an emblem by members of the Kāpālika sect.
Nandī:
Nandī, also known as Nandin, is the name of the bull that serves as Shiva's mount (Sanskrit: vāhana). Shiva's association with cattle is reflected in his name Paśupati, or Pashupati (Sanskrit: पशुपति), translated by Sharma as "lord of cattle"and by Kramrisch as "lord of animals", who notes that it is particularly used as an epithet of Rudra. Rishabha or the bull represents Dharma Devata. Lord Siva rides on the bull. Bull is his vehicle. This denotes that Lord Siva is the protector of Dharma, is an embodiment of Dharma or righteousness.
Gaṇa:
The Gaṇas (Devanagari: गण) are attendants of Shiva and live in Kailash. They are often referred to as the bhutaganas, or ghostly hosts, on account of their nature. Generally benign, except when their lord is transgressed against, they are often invoked to intercede with the lord on behalf of the devotee. Ganesha was chosen as their leader by Shiva, hence Ganesha's title gaṇa-īśa or gaṇa-pati, "lord of the gaṇas".
Mount Kailāsa:
Mount Kailash in the Himalayas is his traditional abode.In Hindu mythology, Mount Kailāsa is conceived as resembling a Linga, representing the center of the universe.
Varanasi:
Varanasi (Benares) is considered as the city specially loved by Shiva, and is one of the holiest places of pilgrimage in India. It is referred to, in religious contexts, as Kashi.
