Gradually Mahārāja Bharata became very affectionate toward the deer. He began to raise it and maintain it by giving it grass. He was always careful to protect it from the attacks of tigers and other animals. When it itched, he petted it, and in this way he always tried to keep it in a comfortable condition. He sometimes kissed it out of love. Being attached to raising the deer, Mahārāja Bharata forgot the rules and regulations for the advancement of spiritual life, and he gradually forgot to worship the Supreme Personality of Godhead. After a few days, he forgot everything about his spiritual advancement.
