Śrīmad-Bhāgavatam · Text 12.3.14
Who is speaking and story frame
कथा इमास्ते कथिता महीयसां
विताय लोकेषु यश: परेयुषाम् ।
विज्ञानवैराग्यविवक्षया विभो
वचोविभूतीर्न तु पारमार्थ्यम् ॥ १४ ॥
kathā imās te kathitā mahīyasāṁ
vitāya lokeṣu yaśaḥ pareyuṣām
vijñāna-vairāgya-vivakṣayā vibho
vaco-vibhūtīr na tu pāramārthyam
Śukadeva Gosvāmī said: O mighty Parīkṣit, I have related to you the narrations of all these great kings, who spread their fame throughout the world and then departed. My real purpose was to teach transcendental knowledge and renunciation. Stories of kings lend power and opulence to these narrations but do not in themselves constitute the ultimate aspect of knowledge.
