śrīgaruḍamahāpurāṇam- 33
garuḍa uvāca /
utpattilakṣaṇaṃ jantoḥ kathitaṃ mayi puttrake /
yamalokaḥ kiyanmātrastrailokye sacarācare /
vistaraṃ tasya me brūhi adhvā caiva kiyān smṛtaḥ //

Śrī Garuḍa said:
The characteristics of the birth of a creature have been told to me, your son.
How large is the world of Yama within the three worlds, including moving and stationary beings?
Tell me its extent, and how long the road is said to be.
