Rakta Arya avalokiteshvara is one of the many forms of Avaloki-teshvara. According to a chronicle, Avalokiteshvara emanated himself as a son of Yaksha in Kamuni Kshetra in Assam. Rakta Arya avalokiteshvara was brought to Kathmandu with great effort by king Narendra Deva, Guru Bandhudatta and a farmer Lalita. In the seventh century Nepal there was a famine for twelve years. People suffered much due to drought. Following the suggestion of Acarya Bandhudutta the act of bringing a child who was the emanation of Arya Avalokiteshvara was carried out successfully. Nepalese people called this deity as Bungadeo. Every year a chariot festival is celebrated with great pomp and splendour in Patan city. All the valley citizens observe this festival with gaiety and happiness.
