Authority - Doctrine and Covenants 12-13
There is a real event that occurs when hands are placed upon heads and authority is endowed, priesthood authority. It is not just a tradition, or ceremony. The act of an authorized minister conferring their authority upon another invokes a power that is difficult to understand, but no less real than the earth we walk on. By that same power was the earth organized and life placed upon it.

An orderly manner that helps us recognize who has received it and acknowledge the consent of he who grants it.

A farmer and a school teacher.
Hebrews 5:4 “And no man taketh this honour unto himself, but he that is called of God, as was Aaron.“

The heavens must have shouted and sang with joy at this event.
