The Supreme Personality of Godhead used the Yadu dynasty, which was protected by His own arms, to eliminate the kings who with their armies had been the burden of this earth. Then the unfathomable Lord thought to Himself, “Although some may say that the earth’s burden is now gone, in My opinion it is not yet gone, because there still remains the Yādava dynasty itself, whose strength is unbearable for the earth.”
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
भूभारराजपृतना यदुभिर्निरस्य गुप्तैः स्वबाहुभिरचिन्तयदप्रमेयः । मन्येऽवनेर्ननु गतोऽप्यगतं हि भारं यद्यादवं कुलमहो अविषह्यमास्ते
