sudurjayaṁ viṣṇu-padaṁ jitaṁ tvayā
 yat sūrayo ’prāpya vicakṣate param
ātiṣṭha tac candra-divākarādayo
 graharkṣa-tārāḥ pariyanti dakṣiṇam
Word for word: 
sudurjayam — very difficult to achieve; viṣṇu-padam — planet known as Vaikuṇṭhaloka or Viṣṇuloka; jitam — conquered; tvayā — by you; yat — which; sūrayaḥ — great demigods; aprāpya — without achieving; vicakṣate — simply see; param — supreme; ātiṣṭha — please come; tat — that; candra — the moon; diva-ākara — sun; ādayaḥ — and others; graha — the nine planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto); ṛkṣa-tārāḥ — stars; pariyanti — circumambulate; dakṣiṇam — to the right.
Translation: 
To achieve Viṣṇuloka is very difficult, but by your austerity you have conquered. Even the great ṛṣis and demigods cannot achieve this position. Simply to see the supreme abode [the Viṣṇu planet], the sun and moon and all the other planets, stars, lunar mansions and solar systems are circumambulating it. Now please come; you are welcome to go there.
Purport: 

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.
