Beyond the 3 modes, Sri Naradamuni, transcendental spaceman!

Verse 1.6.31: Being fixed in unbroken devotional service of the Lord, Sri Naradamuni can travel throughout the spiritual and material worlds.

Srila Prabhupada writes here that since Sri Naradamuni is transcendental to the 3 modes (of which the material world is made), he can do such space travel.
The causeless mercy of Lord Vishnu is unparalleled, and such mercy is perceived by the devotees only by the grace of the Lord. Therefore, the devotees never fall down, but the materialists, i.e., the fruitive workers and the speculative philosophers, do fall down, being forced by their respective modes of nature. The rsis, as above mentioned, cannot enter into the transcendental world like Närada. This fact is disclosed in the Narasimha Purana. Rsis like Marici are authorities in fruitive work, and rsis like Sanaka and Sanätana are authorities in philosophical speculations. But Sri Närada Muni is the prime authority for transcendental devotional service of the Lord. All the great authorities in the devotional service of the Lord follow in the footsteps of Närada Muni in the order of the Närada-bhakti-sütra, and therefore all the devotees of the Lord are unhesitatingly qualified to enter into the kingdom of God, Vaikunta.

Prabhuji, again spoke about gratitude, about how much we should be indebted to be associated with this parampara. The mercy of Srila Prabhupada that we are fortunate enough to receive. We really have to understand its merit to utilize in the proper way. Srila Prabhupada has further said that this movement is given to us so that we can associate with devotees, seriously chant the holy name and make progress in our devotional live.
