Even in this material world the so-called scientists, philosophers and mental speculators strive to merge into the spiritual sky, but they can never go there. But a devotee, by executing devotional service, not only realizes what the spiritual world actually is, but factually goes there to live an eternal life of bliss and knowledge. The Kṛṣṇa consciousness movement is so potent that by adopting these principles of life and developing love of God one can very easily go back home, back to Godhead. Here the practical example is the case of Dhruva Mahārāja. While the scientist and philosopher go to the moon but are disappointed in their attempts to stay there and live, the devotee makes an easy journey to other planets and ultimately goes back to Godhead. Devotees have no interest in seeing other planets, but while going back to Godhead they see all of them as passing phases, just as one who is going to a distant place passes through many small stations.
