Bygone
Bhagavad-gita As It Is
BG Chapters 7 - 12
BG 10.18, Purport:
Now as far as amṛtam, nectar, is concerned, any narration or statement concerning Kṛṣṇa is just like nectar. And this nectar can be perceived by practical experience. Modern stories, fiction and histories are different from the transcendental pastimes of the Lord in that one will tire of hearing mundane stories but one never tires of hearing about Kṛṣṇa. It is for this reason only that the history of the whole universe is replete with references to the pastimes of the incarnations of Godhead. The Purāṇas are histories of bygone ages that relate the pastimes of the various incarnations of the Lord. In this way the reading matter remains forever fresh, despite repeated readings.
