Srimad Bhagavatam Canto 07, Chapter 01, Text 37

SB 7.1.37

pañca-saddhayanarbhabhah
 purvesam api purvajah
dig-vasasah sisun matva
 dvah-sthau tan pratyasedhatam
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Although these four great sages were older than Brahma’s other sons like Marici, they appeared like small naked children only five or six years old. When Jaya and Vijaya saw them trying to enter Vaikunthaloka, these two gatekeepers, thinking them ordinary children, forbade them to enter.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
In this regard, Srila Madhvacarya says in his Tantra-sara:
 
dvah-sthav ity anenadhikara-sthatvam uktam
 
adhikara-sthitas caiva
 vimuktas ca dvidha janah
visnu-loka-sthitas tesam
 vara-sapadi-yoginah
 
adhikara-sthitam muktim
 niyatam prapnuvanti ca
vimukty-anantaram tesam
 vara-sapadayo nanu
 
dehendriyasu-yuktas ca
 purvam pascan na tair yutah
apy abhimanibhis tesam
 devaih svatmottamair yutah
 
The purport is that the personal associates of Lord Visnu in Vaikunthaloka are always liberated souls. Even if sometimes cursed or blessed, they are always liberated and never contaminated by the material modes of nature. Before their liberation to Vaikunthaloka they possessed material bodies, but once they come to Vaikuntha they no longer have them. Therefore even if the associates of Lord Visnu sometimes descend as if cursed, they are always liberated.
