Rāhu, Eclipses, Antarikṣa, and the Seven Subterranean Heavens

na vā eteṣu vasatāṁ divyauṣadhi-rasa-rasāyanānna-pāna-snānādibhir ādhayo vyādhayo valī-palita-jarādayaś ca deha-vaivarṇya-daurgandhya-sveda-klama-glānir iti vayo ’vasthāś ca bhavanti.
Because the residents of those realms drink and bathe in nectarean juices and elixirs made from wondrous herbs, they are free from all anxiety and disease. They know no grey hair, wrinkles, or infirmity; their bodily luster does not fade, their perspiration bears no foul odor, and they are not troubled by fatigue or loss of vigor due to old age.
In Bhagavatam 5.24.13, Śukadeva explains that residents of those regions, due to celestial herbs, elixirs, and luxurious provisions, do not suffer mental distress, disease, or the usual symptoms of aging like wrinkles, gray hair, fatigue, and bodily deterioration.
Śukadeva is narrating the universe’s structure and the varied karmic destinations within it; by describing even extraordinary material comforts, he helps Parīkṣit understand that such enjoyments are still within saṁsāra and are not the ultimate goal compared to pure bhakti.
Even if one gains comfort, health, or long life through rare advantages, these remain temporary material conditions; the verse encourages seekers to prioritize devotion to the Lord over chasing bodily perfection.
