Ramayana
ततो ऽब्रवीन्महातेजा मेघनादं प्रजापतिः । नास्ति सर्वामरत्वं हि कस्यचित्प्राणिनो भुवि । चतुष्पदः पक्षिणश्च भूतानां वा महौजसाम् ॥ 7-30-11 ॥
Then the Lord of Creatures of great splendor spoke to Meghanada: "There is no complete immortality for any living being on earth — neither for four-footed creatures, nor for birds, nor for beings of great might."
