The Upanishads, Part 2 (SBE15), by Max Müller, [1879], at sacred-texts.com

TENTH BRÂHMANA.

1. When the person goes away from this world, he comes to the wind. Then the wind makes room for him, like the hole of a carriage wheel, and through it he mounts higher. He comes to the sun. Then the sun makes room for him, like the hole of a Lambara 2, and through it he mounts higher. He comes to the moon. Then the moon makes room for him, like the hole of a drum, and through it he mounts higher, and arrives at the world where there is no sorrow, no snow 3. There he dwells eternal years.
