ITRANS:

tām anuparito loka-pālānām aṣṭānāṁ yathā-diśaṁ yathā-rūpaṁ turīya-mānena puro ’ṣṭāv upakḷptāḥ.

Translation:

Surrounding Brahmapurī in all directions are the residences of the eight principal governors of the planetary systems, beginning with King Indra. These abodes are similar to Brahmapurī but are one fourth the size.

Purport:

Śrīla Viśvanātha Cakravartī Ṭhākura confirms that the townships of Lord Brahmā and the eight subordinate governors of the planetary systems, beginning with Indra, are mentioned in other Purāṇas. Brahmā’s township is known as Manovatī, and those of his assistants such as Indra and Agni are known as Amarāvatī, Tejovatī, Saṁyamanī, Kṛṣṇāṅganā, Śraddhāvatī, Gandhavatī, Mahodayā and Yaśovatī. Brahmapurī is situated in the middle, and the other eight purīs surround it in all directions.
