IMO

Odumare sat back and thought about how to create more things in his universe. For this purpose, he realized he needed more of an intermediary force, since he was to charged with energy to come in direct contact with any living thing and have it survive. Therefore, he created Agbon (wisdom), held it in his palm and thought where it could live. After a while, Odumare released Agbon to fly away and look for a suitable place to lodge. When Agbon could not find a suitable abode, it flew back humming like a bee to Odumare.Odumare took Agbon and swallowed it. Similarly, Imo (knowledge) and Oye (understanding), which were also created, returned for lack of suitable abodes and swallowed for the same reason.

Odumare then "slept," but not in the human sense of the word:

Seemingly asleep but awake,
Seeming dormant but alive.
Eleye (the witches) swished
their wings against my face.
I asked what my offense was,
Odumare never slumbers.

After several thousand years during which Odumare was disturbed by the incessant humming of Agbon, Imo and Oye, he decided to get rid of them in order to have some peace. He order them to descend (ro) making the sound "hoo." Thus the three heavenly bodies now know as Hoo-ro or Oro were evacuated and set for their descent to earth. Since they were heavenly charged life forces from heaven, their descent was accompanied by lighting and thunder. All solid matter melted and became jelly like. For a while, Oro was suspended in mid air like an egg and did not melt, but then it dropped to earth and split (la).

In Oro's new state it is identified with Ela, the deity which functions in the Ifa divination complex and is regarded by the Yoruba as the embodiment of wisdom, knowledge and understanding in all their forms.
