Keshi's death broke the back of Kans. He could not think of any warrior who could undertake the task of putting Krishna to death. So, he decided to take recourse to treachery in order to achieve his objective of killing his nephew Krishna.
Akrur, chief of the charity department of Kans, was a very saintly person. Kans asked him to go to Vrindavan and bring Nand Baba's family and other respectable Gops to participate in the Bow-yajna. A saintly person as he was, Akrur gladly agreed to go to Vrindavan. He had a keen desire to see Krishna, who is Purna Prusotam, Himself. So, riding a chariot, he proceeded to Vrindavan.
Reaching the outskirts of Vrindavan, Akrur caught sight of Krishna's footprints and his heart began to overbubble with devotion for Krishna. Stopping the chariot there, he got down and seeing Krishna's footprints with tearful eyes, paid obeisance to them. He felt proud of being lucky enough to have a chance to do this religious act. Akrur, then, reached Nand Baba's house and delivered Kans's message to him. Nand Baba entertained him duly. Akrur disclosed everything about Kans's treacherous plot to kill Krishna.
