Brihadaranyaka Upanishad 5.10.1

5.10.1

yadā vai puruṣo'smāllokātpraiti sa vāyumāgacchati tasmai sa tatra vijihīte yathā rathacakrasya khaṃ tena sa ūrdhva ākramate sa ādityamāgacchati tasmai sa tatravijihīte yathā lambarasya khaṃ tena sa ūrdhva ākramate sa candramasamāgacchati tasmai sa tatra vijihīte yathā dundubheḥ khaṃ tena sa ūrdhva ākramate sa lokamāgacchatyaśokamahimaṃ tasminvasati śāśvatīḥ samāḥ

When a man departs from this world, he reaches the air, which makes an opening there for him like the hole of a chariot-wheel. He goes upwards through that and reaches the sun, who makes an opening there for him like the hole of a tabor. He goes upwards through that and reaches the moon, who makes an opening there for him like the hole of a drum. He goes upwards through that and reaches a world free from grief and from cold. He lives there for eternal years.
