Heimdall sits upright, always awake and watching, against the end of heaven, listening to grass grow and wool grow on sheep. There, watching, he is peaceful and at ease, and sees everything in front of him. Once, he came amongst men and gave them good counsels, raising leaders familiar with spirituality (runes of eternity) and pragmatic wisdom (runes of men). Because of his formative influence on religion, he is said to rule the temples, where an eternal flame always sits.
It would seem the pragmatic wisdom related to agriculture (the sheaf of grain he brought), artisanship (the tools he brought), homemaking and the hearth (the fire he brought), and defense of the folk (the shield he brought).
Three of Heimdall's epithets (Heimdali, Veður, and Hallinskíði) all refer to a "ram", which strongly suggests he was imagined in terms of a ram. A ram is the leader of a sheep-pack, the natural shepherd of the herd. He is thus a kind of good shepherd of men.
Heimdall is the Warrior Buddha of the Norse tradition, the Surak who brought us logic, the Father of all, High and Low. He is the presence in the fire, the watcher behind and within the sacrifice, the first Gothi of men in times of old.
