Once, wishing to feed Krishna with butter, Yashoda began to churn milk in the morning . Very soon, Krishna too awakened and not finding the mother on her bed, He set out to search her. Soon He found her in the courtyard where she was churning the milk. He began to insist for breast feeding at once. So Yashoda stopped churning and began to breast feed Krishna. Affection played on her face. Suddenly the milk kept on the fire pot began to boil. Yashoda left Krishna in order to attend the boiling milk. But the unstated Krishna filled with anger and broke the pitcher of curd. Then he went inside and began to eat butter, when Yashoda came back, she understood the matter and began to search him with a stick in her hand. After eating butter himself, Krishna was now feeding the monkeys with it. Seeing the mother come in hot pursuit, Krishna jumped over the mortar and ran away. Yashoda chased him, but soon felt tired because of her bulky body.
Thereafter, Yashoda proceeded to tie Krishna as a punishment. She got a rope and tried to tie Krishna. But the rope fell short by two fingers. She joined many ropes together but the result was same. Every time the ropes fell short by two fingers. Soon, Yashoda was bathing in sweat. When Krishna saw his mother in depression, he himself tied in the ropes. Tethering little Krishna to a heavy mortar, Yashoda engaged in usual household tasks. Tethered to the mortar, Krishna glanced at the two Arjuna trees, which were standing on the gate like two sentries. He resolved to save them.
King Parikshit asked Sukhdev about the trees. Sukhdev said: “Parikshit, the lord of wealth Kubera had two sons Nalkuber and Manigreeva. One day they were enjoying the sweet company of pretty women on the bank of Mandakini river. Just by coincidence, Devarshi Narada arrived there. Out of Shyness, the women folk at once covered themselves, but both the sons of Kubera stood boldly without feeling any shame. Indignant Narada cursed them to become trees and stay in that form for one hundred years. Narada showed kindness as well that despite being in tree forms, they would have the memory of God alive and would be saved by Lord Sri Krishna. Thus, to keep the words of his supreme devotee Narada, Lord dragged the mortar to the two Arjuna trees. He walked in such a way that the mortar got stuck between the trees. Krishna then pulled the mortar and in no time the trees were uprooted. Two divine men appeared from the uprooted trees and bowed at the feet of Krishna and prayed him with pure hearts. Then they departed to their heavenly abode.
