O Nanda Maharaja, as recorded in history, when there was an irregular, incapable government, Indra having been dethroned, and people were being harassed and disturbed by thieves, this child appeared in order to protect the people and enable them to flourish, and He curbed the rogues and thieves.
Indra is the king of the universe. Demons, thieves and rogues always disturb Indra (indrari-vyakulam lokam), but when indraris, the enemies of Indra, become prominent, Krsna appears. Krsnas tu bhagavan svayam/ indrari-vyakulam lokam mrdayanti yuge yuge (Bhag. 1.3.28).
