The Future Manus and the Avatāras in Their Manvantaras
पवित्राश्चाक्षुषा देवा: शुचिरिन्द्रो भविष्यति । अग्निर्बाहु: शुचि: शुद्धो मागधाद्यास्तपस्विन: ॥ ३४ ॥
pavitrāś cākṣuṣā devāḥ śucir indro bhaviṣyati agnir bāhuḥ śuciḥ śuddho māgadhādyās tapasvinaḥ
The Pavitras and Cākṣuṣas will be among the demigods, and Śuci will be Indra. Agni, Bāhu, Śuci, Śuddha, Māgadha and other great ascetics will be the seven sages.
The Pavitrās are the group of demigods who appear in that manvantara and are described as descendants connected with Cākṣuṣa Manu.
This verse states that Śuci will take the post of Indra (the ruler of Svarga) during that period, indicating the changing of cosmic administrators across manvantaras.
It highlights impermanence: even the highest worldly posts change with time, encouraging one to seek lasting refuge in devotion to Bhagavān rather than temporary status.
