Once we go to Goloka we never return to this cycle of birth & death

[Guest guest]

prema-laksanayA bhaktyA

mad-dhAma prakrteh param

prApsyasi tvam mahA-rAja

yato nAvartate gatAh

 

[yatah- from which, na- not, avartate- returns, gatah - having gone]

 

O great king, by serving Me with loving devotion You will

attain My own abode, which is above the world of matter. They who

go there never return to the world of birth and death.

 

Krsna assures King Mucukunda, from Garga Samhita translated by KD.
