SB 11.6.31
idanim nasa arabdhah
kulasya dvija-sapa-jah
yasyami bhavanam brahmann
etad-ante tavanagha
Translation:
Now due to the brahmanas’ curse, the annihilation of My family has already begun. O sinless Brahma, when this annihilation is finished and I am enroute to Vaikuntha, I will pay a small visit to your abode.
Purport:
The members of the Yadu dynasty are eternal servants of the Lord; therefore Srila Jiva Gosvami has explained the word nasah, or “destruction,” as nigudhayam dvarakayam pravesanam ity arthah: the members of the Yadu dynasty entered into the hidden or confidential Dvaraka in the spiritual world, which is not manifested here on the earth. In other words, Dvaraka, the Lord’s abode, is manifest on the earth, and when the earthly Dvaraka is apparently removed, the eternal Dvaraka in the spiritual world remains as it is. Since the members of the Yadu dynasty are eternal associates of the Lord, there is no question of their destruction. Only our conditioned vision of their manifestation was destroyed. This is the meaning of the word nasah.
