Every year around the time when the sky is covered with kites, and the Durga puja is near comes the Vishwakarma Puja. Vishwakarma is the god of artists and creators, who is believed to be the designer and builder of palaces, chariots and weapons. Vishwakarma is the architect of the universe and the patron deity of craftsmen. According to the Mahabharata, Vishwakarma built the halls of the palaces and all kinds of ornaments.
According to Mahabharata, Vishwakarma has four arms, the king's crown on the head, in one hand a pitcher of water and in another hand filled with books, uttariya and an instrument in another hand.
According to Hindu mythology, Vishwakarma designed the spectacular and revered cities of Dwarka, which Krishna mentioned as karmabhumi, mayanagari Indraprastha, with waterbodies and palace grounds glittering like glass and ponds with clear water, and Hastinapur, the capital of Pandavas and the palace of Ravana in Lanka.
He built the universe by performing a great sacrifice and by sacrificing himself. Through the ages, he built cities and palaces. He built the sky, home of the gods in the Satya Yuga, the golden palace of Shiva in Treta Yuga, the city of Dwarka in Dvapara Yuga and the cities of Hastinapur and Indraprastha in Kali Yuga.
Often mentioned in the epics, this god is however underrepresented. According to the myths, Vishwakarma, the architect of the gods, built Kubera, the god of wealth and treasurer of the gods and guardian of yaksha (wild beings) a palace on the sacred Mount Kailash and a garden called Shaitartha on mythical Mount Mandara. Kubera kept their his earthly treasures of minerals, precious stones, metals.
In Ellora is the famous Vishwakarma cave, or the cave of the carpenter where you can observe a statue of Buddha and the Kailasa temple, a temple-like building, completely excavated from the cliff, the size far exceeds that of the Parthenon in Athens.
Vishwakarma Puja is mostly observed in Bengal and is celebrated on the last day of Bhadra month and in that day, no tool can be used.
