iti vyavasitam tasya
darsayam asatur devim
puro yanena gacchatim
iti—thus; vyavasitam—contemplation; tasya—of Dhruva; vyavasaya—understanding; sura-uttamau—the two chief associates; darsayam asatuh—showed (to him); devim—exalted Suniti; purah—before; yanena—by airplane; gacchatim—going forward.
The great associates of Vaikunthaloka, Nanda and Sunanda, could understand the mind of Dhruva Maharaja, and thus they showed him that his mother, Suniti, was going forward in another plane.
This incident proves that the siksa- or diksa-guru who has a disciple who strongly executes devotional service like Dhruva Maharaja can be carried by the disciple even though the instructor is not as advanced. Although Suniti was an instructor to Dhruva Maharaja, she could not go to the forest because she was a woman, nor could she execute austerities and penances as Dhruva Maharaja did. Still, Dhruva Maharaja was able to take his mother with him. Similarly, Prahlada Maharaja also delivered his atheistic father, Hiranyakasipu. The conclusion is that a disciple or an offspring who is a very strong devotee can carry with him to Vaikunthaloka either his father, mother or siksa- or diksa-guru. Srila Bhaktisiddhanta Sarasvati Thakura used to say, “If I could perfectly deliver even one soul back home, back to Godhead, I would think my mission—propagating Krsna consciousness—to be successful.” The Krsna consciousness movement is spreading now all over the world, and sometimes I think that even though I am crippled in many ways, if one of my disciples becomes as strong as Dhruva Maharaja, then he will be able to carry me with him to Vaikunthaloka.
