Pushpak Viman was created by the divine architect Vishwakarma for Bramha Ji. The god of Wealth, Kuber attains it from Bramha Ji after pleasing the latter with his penance and austerities.
Later, Ravan snatches the Pushpak from Kuber and takes it for himself. This Pushpak Viman was capable of flying anywhere in the world. It was endowed with great aircraft technique and snatching it through his sorcery, Ravan believes himself to be the master of the three worlds. Many of his encounters with Bhagwan Shiv, Kartaveeryarjun, Bali and likewise had happened when he was traveling all the three worlds in the Pushpak Viman.
The architectural marvel of the Pushpak Viman is mentioned in the Yuddh Kand. Hanuman while searching for Sita, comes across the Pushpak Viman and he is astonished at its craft work. He sees the Pushpak with its golden shine and it amazes him. There were crystals and precious stones in abundance there, trees with flowers and the images of Goddess Lakshmi and it was floating in the air, instead of standing on the ground. It looked like a palace in the sky.
