SB 6.5.13
puman naivaiti yad gatva
bila-svargam gato yatha
pratyag-dhamavida iha
kim asat-karmabhir bhavet
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
[Narada Muni had described that there is a bila, or hole, from which, having entered, one does not return. The Haryasvas understood the meaning of this allegory.] Hardly once has a person who has entered the lower planetary system called Patala been seen to return. Similarly, if one enters the Vaikuntha-dhama [pratyag-dhama], he does not return to this material world. If there is such a place, from which, having gone, one does not return to the miserable material condition of life, what is the use of jumping like monkeys in the temporary material world and not seeing or understanding that place? What will be the profit?
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
As stated in Bhagavad-gita (15.6), yad gatva na nivartante tad dhama paramam mama: there is a region from which, having gone, one does not return to the material world. This region has been repeatedly described. 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.”
If one can properly understand Krsna, who has already been described as the Supreme King, he does not return here after giving up his material body. This fact has been described in this verse of Srimad-Bhagavatam. Puman naivaiti yad gatva: he does not return to this material world, but returns home, back to Godhead, to live an eternally blissful life of knowledge. Why do people not care about this? What will be the benefit of taking birth again in this material world, sometimes as a human being, sometimes a demigod and sometimes a cat or dog? What is the benefit of wasting time in this way? Krsna has very definitely asserted in Bhagavad-gita (8.15):
mam upetya punar janma
duhkhalayam asasvatam
napnuvanti mahatmanah
samsiddhim paramam gatah
“After attaining Me, the great souls, who are yogis in devotion, never return to this temporary world, which is full of miseries, because they have attained the highest perfection.” One’s real concern should be to free himself from the repetition of birth and death and attain the topmost perfection of life by living with the Supreme King in the spiritual world. In these verses the sons of Daksa repeatedly say, kim asat-karmabhir bhavet: “What is the use of impermanent fruitive activities?”
