The Moon became Mind, and Entered the Heart.

Atman, the Creator, made Fire, Wind, Sun, Moon, and other divinities.

They said to him: ‘Find out for us an abode wherein we may be established and may eat food.’ He led up a bull to them. They said: ‘Verily, this is not sufficient for us.’ He led up a horse to them. They said: ‘Verily, this is not sufficient for us.’ He led up a person to them. They said: ‘Oh! well done!’—Verily, a person is a thing well done.— He said to them: ‘Enter into your respective abodes.’

Fire became speech, and entered the mouth.

Wind became breath, and entered the nostrils.

The Sun became sight, and entered the eyes.

The Moon became mind, and entered the heart.
