SB 1.17.12
ko ’vrscat tava padams trin
saurabheya catus-pada
ma bhuvams tvadrsa rastre
rajñam krsnanuvartinam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
He [Maharaja Pariksit] repeatedly addressed and questioned the bull thus: O son of Surabhi, who has cut off your three legs? In the state of the kings who are obedient to the laws of the Supreme Personality of Godhead, Krsna, there is no one as unhappy as you.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The kings or the executive heads of all states must know the codes of Lord Krsna (generally Bhagavad-gita and Srimad-Bhagavatam) and must act accordingly in order to fulfill the mission of human life, which is to make an end to all miseries of material conditions. One who knows the codes of Lord Krsna can achieve this end without any difficulty. In the Bhagavad-gita, in a synopsis, we can understand the codes of Godhead, and in the Srimad-Bhagavatam the same codes are explained further.
In a state where the codes of Krsna are followed, no one is unhappy. Where such codes are not followed, the first sign is that three legs of the representative of religion are cut off, and thereby all miseries follow. When Krsna was personally present, the codes of Krsna were being followed without question, but in His absence such codes are presented in the pages of Srimad-Bhagavatam for the guidance of the blind persons who happen to be at the helm of all affairs.
