ŚVETĀŚVATARA UPANISHAD · 2.12

पृथ्व्यप्तेजोऽनिलखे समुत्थिते पञ्चात्मके योगगुणे प्रवृत्ते ।
न तस्य रोगो न जरा न मृत्युः प्राप्तस्य योगाग्निमयं शरीरम् ॥

pṛthvyaptejo’nilakhe samutthite pañcātmake yogaguṇe pravṛtte ।
na tasya rogo na jarā na mṛtyuḥ prāptasya yogāgnimayaṃ śarīram ॥

When, as earth, water, light, heat, and ether arise, the fivefold quality of Yoga takes place, then there is no longer illness, old age, or pain for him who has obtained a body, produced by the fire of Yoga.
