Since the residents of these planets drink and bathe in juices and elixirs made from wonderful herbs, they are freed from all anxieties and physical diseases. They have no experience of grey hair, wrinkles or invalidity, their bodily lusters do not fade, their perspiration does not cause a bad smell, and they are not troubled by fatigue or by lack of energy or enthusiasm 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.
