Srimad Bhagavatam Canto 01, Chapter 18, Text 35

SB 1.18.35

krsne gate bhagavati
sastary utpatha-gaminam
tad bhinna-setun adyaham
sasmi pasyata me balam
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
After the departure of Lord Sri Krsna, the Personality of Godhead and supreme ruler of everyone, these upstarts have flourished, our protector being gone. Therefore I myself shall take up this matter and punish them. Just witness my power.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The inexperienced brahmana, puffed up by a little brahma-tejas, became influenced by the spell of Kali-yuga. Maharaja Pariksit gave license to Kali to live in four places as mentioned hereinbefore, but by his very expert government the personality of Kali could hardly find the places allotted him. The personality of Kali-yuga, therefore, was seeking the opportunity to establish authority, and by the grace of the Lord he found a hole in the puffed-up, inexperienced son of a brahmana. The little brahmana wanted to show his prowess in destruction, and he had the audacity to punish such a great king as Maharaja Pariksit. He wanted to take the place of Lord Krsna after His departure. These are the principal signs of upstarts who want to take the place of Sri Krsna under the influence of the Age of Kali. An upstart with a little power wants to become an incarnation of the Lord. There are many false incarnations after the departure of Lord Krsna from the face of the globe, and they are misleading the innocent public by accepting the spiritual obedience of the general mass of people to maintain false prestige. In other words, the personality of Kali got the opportunity to reign through this son of a brahmana, Srngi.
