ehyehīti tamāhutayaḥ suvarcasaḥ sūryasya raśmibhiryajamānaṃ vahanti। priyāṃ vācamabhivadantyo'rcayantyaḥ eṣa vaḥ puṇyaḥ sukṛto brahmalokaḥ ॥6॥

The 'brahmalokaḥ' mentioned in the context is the supreme world of Brahman. It is got by performing virtuous deeds related to topics concerning the Lord. Various testimonials are quoted to emphasize that even while one delights in ātman within, the wise person should act and perform his duties unattached, worshiping the Ātmān only as the world.
