When Dhruva Mahārāja was in the forest executing his austerities, his father, Uttānapāda, heard everything about his very wonderful activities. Although Dhruva Mahārāja was the son of a king and was only five years old, he went to the forest and executed devotional service under strict austerity. Therefore his acts were all wonderful, and when he came back home, naturally, because of his spiritual qualifications, he became very popular amongst the citizens. He must have performed many wonderful activities by the grace of the Lord. No one is more satisfied than the father of a person who is credited with glorious activities. Mahārāja Uttānapāda was not an ordinary king; he was a rājarṣi, a saintly king. Formerly this earth was ruled by one saintly king only. Kings were trained to become saintly; therefore they had no other concern than the welfare of the citizens. These saintly kings were properly trained, and as mentioned in Bhagavad-gītā also, the science of God, or the yoga system of devotional service known as Bhagavad-gītā, was spoken to the saintly king of the sun planet, and gradually it descended through the kṣatriya kings who were generated from the sun and the moon. If the head of the government is saintly, certainly the citizens become saintly, and they are very happy because both their spiritual and physical needs and hankerings are satisfied.
