A Shiva Astra is an Astra which symbolizes the weapons and powers used by the Shiva, the "Destroyer" in Hinduism, the god of wind, dance, war, and destruction.
Having many different attributes, allows a magician to wield many different Astras based on a single god.
Trishula, the trident of the Hindu deity Shiva, stylized by some as used as a missile weapon and often included a crossed stabilizer to facilitate flight when thrown. Considered to be the most powerful weapon.
The trishula symbolism is polyvalent and rich. The trishula is wielded by the Hindu God Shiva and is said to have been used to sever the original head of Ganesha. Durga also holds trishula, as one of her many weapons. There are many other gods and deities, who hold the weapon trishula. The three points have various meanings and significance, and, common to Hindu religion, have many stories behind them. They are commonly said to represent various trinities—creation, maintenance and destruction, past, present and future, the three guna. When looked upon as a weapon of Shiva, the trishula is said to destroy the three worlds: the physical world, the world of the forefathers (representing culture drawn from the past) and the world of the mind (representing the processes of sensing and acting). The three worlds are supposed to be destroyed by Shiva into a single non-dual plane of existence, that is bliss alone.
In the human body, the trishula also represents the place where the three main nadis, or energy channels (ida, pingala and shushmana) meet at the brow. Shushmana, the central one, continues upward to the 7th chakra, or energy center, while the other two end at the brow, there the 6th chakra is located. The trisula's central point represents Shushmana, and that is why it is longer than the other two, representing ida and pingala.
The Pashupatastra ( पाशुपतास्त्र) is the irresistible and most destructive personal weapon of Shiva, discharged by the mind, the eyes, words, or a bow. Never to be used against lesser enemies or by lesser warriors, the Pashupatastra is capable of destroying creation and vanquishing all beings. Pashupatinath is the most important of all Shiva temples located in Kathmandu, Nepal. Pashupatastra is the weapon of PashupatiNath.
This Pashupatastra was used in the Mahabharata war by Arjuna to kill Jayadratha. It was used against Lakshmana by Meghanada. It returned without causing any harm since it can be used only to uphold Dharma
The parashu (Sanskrit: paraṣu) is an Indian battle-axe. It is generally wielded with two hands but could also be used with only one.
The parashu could be double edged or bladed or single-bladed with a spike on the non cutting edge. It usually measures between 3 – 5 feet though some are as long as 7 feet. The parashu is usually made of iron or wootz steel. The cutting edge is broader than the edge which is attached to the haft. The haft is often tied with a leather sheet to provide a good grip.
The parashu is the weapon of Lord Shiva who gave it to Parashurama, sixth Avatar of Vishnu, whose name means "Rama with the axe" and also taught him its mastery. He was one of the few Brahmin guru who were also masters of hand to hand combat. He is known as the founder of Kalaripayattu, ancient Indian martial art. Parashurama was the guru of Dronacharya, the guru who instructed the Pandavas in the epic of the Mahabharata. Bhishma and Karna, half brother of Pandava also took instruction in weaponry from Parashurama, a disciple of lord Shiva, and was known to have terrible temper having lost his father to the evil Asura. In his anger, Parashurama used the parashu to get rid of the all the Earth's tyrannical kshatriya (warrior class) twenty one times over. Parashurama's weapon had supernatural powers. It had four cutting edges, one on each end of the blade head and one on each end of the shaft.
The parashu was known as the most lethal close combat weapons of the epics. It is also one of the weapons of Lord Shiva and Goddess Durga and is still depicted on their idols throughout India.
Pinaka is the name of the divine bow (dhanush) wielded by Lord Shiv. 8 meter in height.
The Lord of Dance, in Hindu mythology is another name for Shiva, the cosmic dancer who performs his divine dance to destroy a weary universe and make preparations for the god Brahma to start the process of creation. As an Astra of Gate of the Gods Come from the Heavens, it allows the user to use various spells by expressing them in the form of dance.
