The story now enters its second phase. Krishna is no longer a mischievous baby, indulging in tantrums yet wringing the heart with his childish antics. He is now five years old and of an age to make himself useful. He asks to be allowed to graze the calves. At first Yasoda is unwilling. 'We have got so many servants,' she says. 'It is their job to take the calves out. Why go yourself? You are the protection of my eye-lids and dearer to me than my eyes.' Krishna, however, insists and in the end she entrusts him and Balarama to the other young cowherds, telling them on no account to leave them alone in the forest, but to bring them safely home. Her words are, in fact, only too necessary, for Kansa, the tyrant king, is still in quest of the child who is to kill him. His demon minions are still on the alert, attacking any likely boy, and as Krishna plays with the cowherds and tends the calves, he suffers a further series of attacks. A cow demon, Vatsasura, tries to mingle with the herd. The calves sense its presence and as it sidles up, Krishna seizes it by the hind leg, whirls it round his head and dashes it to death. A crane demon, Bakasura, then approaches. The cowherds recognize it, but while they are wondering how to escape, the crane opens its beak and engulfs Krishna. Krishna, however, becomes so hot that the crane cannot retain him. It lets him go. Krishna then tears its beak in two, rounds up the calves and taking the cowherd boys with him, returns home. Another day Krishna is out in the forest with the cowherds and the calves, when a snake demon, Ugrasura, sucks them into its mouth. Krishna expands his body to such an extent that the snake bursts. The calves and cowherd children come tumbling out and all praise Krishna for saving them. On the way back, Krishna suggests that they should have a picnic and choosing a great _kadam_ tree, they sweep the place clean, set out their food and proceed to enjoy it. As they eat, the gods look down, noting how handsome the young Krishna has grown. Among the gods is Brahma, who decides to tease Krishna by hiding the calves while the cowherd children are eating.[19] He takes them to a cave and when Krishna goes in search of them, hides the cowherd children as well. Krishna, however, is not to be deterred. Creating duplicates of every calf and boy he brings them home. No one detects that anything is wrong and for a year they live as if nothing has happened. Brahma has meanwhile sunk himself in meditation, but suddenly recalls his prank and hurries out to set matters right. He is astonished to find the original calves and children still sleeping in the cave, while their counterparts roam the forest. He humbly worships Krishna, restores the original calves and children and returns to his abode. When the cowherd children awake, Krishna shows them the calves. No one realizes what has happened. The picnic continues and laughing and playing they go home.
