Srimad-Bhagavatam: Canto 9 - Chapter 1 - Verse 29
Sanskrit:
भरतस्य महत् कर्म न पूर्वे नापरे नृपा: ।नैवापुर्नैव प्राप्स्यन्ति बाहुभ्यां त्रिदिवं यथा ॥ २९ ॥
ITRANS:
bharatasya mahat karmana pūrve nāpare nṛpāḥnaivāpur naiva prāpsyantibāhubhyāṁ tridivaṁ yathā
Translation:
As one cannot approach the heavenly planets simply by the strength of his arms (for who can touch the heavenly planets with his hands?), one cannot imitate the wonderful activities of Mahārāja Bharata. No one could perform such activities in the past, nor will anyone be able to do so in the future.
