Srimad Bhagavatam Canto 04, Chapter 12, Text 16

SB 4.12.16

atma-stry-apatya-suhrdo balam rddha-kosam
antah-puram parivihara-bhuvas ca ramyah
bhu-mandalam jaladhi-mekhalam akalayya
kalopasrstam iti sa prayayau visalam
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Thus Dhruva Maharaja, at the end, left his kingdom, which extended all over the earth and was bounded by the great oceans. He considered his body, his wives, his children, his friends, his army, his rich treasury, his very comfortable palaces and his many enjoyable pleasure-grounds to be creations of the illusory energy. Thus in due course of time he retired to the forest in the Himalayas known as Badarikasrama.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
In the beginning of his life, when he went to the forest in search of the Supreme Personality of Godhead, Dhruva Maharaja realized that all bodily conceptions of pleasure are products of the illusory energy. In the very beginning, of course, he was after the kingdom of his father, and in order to get it he went to search for the Supreme Lord. But he later realized that everything is the creation of the illusory energy. From the acts of Srila Dhruva Maharaja we can understand that somehow or other if one becomes Krsna conscious — it does not matter what his motivation is in the beginning — he will eventually realize the real truth by the grace of the Lord. In the beginning, Dhruva Maharaja was interested in the kingdom of his father, but later he became a great devotee, maha-bhagavata, and had no interest in material enjoyment. The perfection of life can be achieved only by devotees. Even if one completes only a minute percentage of devotional service and then falls down from his immature position, he is better than a person who fully engages in the fruitive activities of this material world.
