Tvastar - The Creator God
Also known as Tvashtri, Tastar and Tavashtar, Tvastar is heavenly builder or carpenter, many times confused with Viswakarma, the celestial architect. Viswakarma was an invisible form and he created Tvastar from his navel with a visible body. Tvastar is also a part of the creativity of Viswakarma.
Tvastar is the first born creator of the universe. He is the divine builder who along with Viswakarma designed many weapons, chariots and palaces. He is sometimes depicted as a disembodied hand with the power to create and is the maker of divine implements. He is mostly depicted as a four armed God with a fire device in one hand and a ladle in another. The two of his front hands hold one lotus each.
Tvastar in Mahabharata
Mahabharata is a Hindu epic in which the name of Tvastar has been used as a solar deity. He is an Aditya, a child born with the union of a sage named Kashyapa and the mother of Gods, Aditi. Mahabharata gives him the status of one of the ultimate creators who made the three worlds i.e., earth, hell and heaven with the pieces of Surya, the Sun God. Being a solar deity, he is also praised for his power and strength.
Tvastar and Rigveda
Rigveda is one of the earliest Sanskrit scripture on Hinduism. According to Rigveda, Tvastar is Sukracharya’s son (Sukracharaya is the personification of planet Venus and he was also the teacher of Asuras, demonic clan). He belongs to the Bhrigus clan (BhriguBhrigu
Bhrigu was one of the seven great sages known as Saptarishis and was created... was one of the famous seven sages, also known as the Saptarishis).
Tvastar and his Children
Tvastar was the father of Saranyu, a beautiful princess who was married to the Sun God and gave birth to many of his grandsons and a granddaughter. He was also the father of Visvarupa, a three headed son which was created to dethrone Indra (God of Thunder and Lightning) from heaven. Indra was scared of him and finally killed him. To avenge the death of his son, Tvastar created a fiery dragon named Vritra. He was the personification of drought that could block the course of rivers and thus rejecting the power of Indra. But Vritra was slayed by Indra too.
Lord of the Womb
Tvastar not only created inanimate objects, but had the power to make living beings too. Thus he is prayed to pregnant ladies for a healthy offspring and given the name garbha-pati (Lord of the womb).
