In the Vaikuṇṭha world all the living entities are in oneness with the Supreme Godhead because they never defy His orders. Here in the material world, however, they are not sammata, agreeable, but always asammata, disagreeable. This human form of life is a chance to be trained to be agreeable to the orders of the Supreme Lord. To bring about this training in society is the mission of the Kṛṣṇa consciousness movement. As stated in the Bhagavad-gītā, the laws of material nature are very strict; no one can overcome the stringent laws of material nature. But one who becomes a surrendered soul and agrees to the order of the Supreme Lord can easily overcome those stringent laws. The example of Dhruva Mahārāja is very fitting. Simply by becoming agreeable to the orders of the Supreme Personality of Godhead and by developing love of Godhead, Dhruva got the chance to personally meet the confidential servants of Lord Viṣṇu face to face. What was possible for Dhruva Mahārāja is possible for everyone. Anyone who very seriously engages in devotional service can obtain, in due course of time, the same perfection of the human form of life.
