in the priestly rites inspires religious ecstasy. This drinking of the sōma-juice is already an ancient and important feature in the worship of our Aryans, as it is also among their kinsmen in Iran; so it is no wonder that the spirit of the sacred plant has been made by the priests into an important deity and celebrated with endless abundance of praise and prayer. As with Agni, Sōma's appearance and properties are described with inexhaustible wealth of epithets and metaphors. The poets love to dwell on the mystic powers of this wonderful potion, which can heal sickness of soul and body and inspire gods and men to mighty deeds and holy ecstasy. Most often they tell how the god Indra drank huge potions of it to strengthen himself for his great fight with the dragon Vṛitra. Most of this worship is of priestly invention; voluminous as its rhetoric is, it makes no great impression on the laity, nor perhaps on the clergy either. Some of the more ingenious of the priests are already beginning to trace an affinity between Sōma and the moon. The yellow sōma-stalks swell in the water of the pressing-vat, as the yellow moon waxes in the sky; the sōma has a magical power of stimulation, and the moon sends forth a mystic liquid influence over the vegetation of the earth, and especially over magic plants; the sōma is an ambrosia drunk by gods and heroes to inspire them to mighty deeds, and the moon is a bowl of ambrosia
