PURPORT

Just as Krsna does not take a step away from Vrndavana, Krsna's devotee also does not like to leave Vrndavana. However, when he has to tend to Krsna's business, he leaves Vrndavana. After finishing his mission, a pure devotee returns home, back to Vrndavana, back to Godhead. Krsna assured Radharani that after killing the demons outside Vrndavana, He would return. "I am coming back very soon," He promised, "as soon as I have killed the few remaining demons."
