is no reason, so far as I see, to regard Gotama as a mythical solar hero, but the celestial Buddhas[78] clearly have many solar attributes. This is natural. Solar deities are so abundant in Vedic mythology that it is hardly possible to be a benevolent god without having something of the character of the sun. The stream of foreign religions which flowed into India from Bactria and Persia about the time of the Christian era brought new aspects of sun worship such as Mithra, Helios and Apollo and strengthened the tendency to connect divinity and light. And this connection was peculiarly appropriate and obvious in the case of a Buddha, for Buddhas are clearly revealers and light-givers, conquerors of darkness and dispellers of ignorance. Amitâbha (or the Buddha of measureless light), rising suddenly from an obscure origin, has like Avalokita and Vishnu become one of the great gods of Asia. He is also known as Amitâyus or measureless life, and is therefore a god of light and immortality. According to both the Lotus and the Smaller Sukhâvatî-vyûha he is the lord of the western quarter but he is unknown to the Lalita-vistara. It gives the ruler of the west a lengthy title,[79] which suggests a land of gardens. Now Paradise, which has biblical authority as a name for the place of departed spirits, appears to mean in Persian a park or enclosed garden and the Avesta speaks of four heavens, the good thought Paradise, the good word Paradise, the good deed Paradise and the Endless Lights.[80] This last expression bears a remarkable resemblance to the name of Amitâbha and we can understand that he should rule the west, because it is the home to which the sun and departed spirits go. Amitâbha's Paradise is called Sukhâvatî or Happy Land. In the Puranas the city of Varuṇa (who is suspected of having a non-Indian origin) is said to be situated in the west and is called Sukha (Linga P. and Vayu P.) or Mukhya (so Vishnu P. and others). The name Amitâbha also occurs in the Vishnu Purana as the name of a class of gods and it is curious that they are in one place[81] associated with other deities called the Mukhyas. The worship of Amitâbha, so far as its history can be traced, goes back to Saraha, the teacher of Nâgârjuna. He is said to have been a Sudra and his name seems un-Indian. This supports the theory that this worship was foreign and imported into India.[82]
