Srimad Bhagavatam Canto 07, Chapter 01, Text 34

SB 7.1.34

sri-yudhisthira uvaca
kidrsah kasya va sapo
 hari-dasabhimarsanah
asraddheya ivabhati
 harer ekantinam bhavah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Maharaja Yudhisthira inquired: What kind of great curse could affect even liberated visnu-bhaktas, and what sort of person could curse even the Lord’s associates? For unflinching devotees of the Lord to fall again to this material world is impossible. I cannot believe this.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
In Bhagavad-gita (8.16) the Lord clearly states, mam upetya tu kaunteya punar janma na vidyate: one who is purified of material contamination and returns home, back to Godhead, does not return to this material world. Elsewhere in Bhagavad-gita (4.9) Krsna says:
 
janma karma ca me divyam
 evam yo vetti tattvatah
tyaktva deham punar janma
 naiti mam eti so ’rjuna
 
“One who knows the transcendental nature of My appearance and activities does not, upon leaving the body, take his birth again in this material world, but attains My eternal abode, O Arjuna.” Maharaja Yudhisthira, therefore, was surprised that a pure devotee could return to this material world. This is certainly a very important question.
