"The sun is the prana of the universe,
And it rises to bring light to our eyes.
The earth draws the lower fire of apana;
The space between sun and earth is samana,
And the moving air is vyana.
"Fire is udana. When that fire goes out,
The senses are drawn back into the mind
And the person is ready for rebirth.
"Whatever the content of consciousness
At the time of death, that is what unites us
To prana, udana, and the Self,
To be reborn in the plane we have earned."
