SB 9.20.29
bharatasya mahat karma
na purve napare nrpah
naivapur naiva prapsyanti
bahubhyam tridivam yatha
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
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 Maharaja Bharata. No one could perform such activities in the past, nor will anyone be able to do so in the future.
