Translation: 
[Lord Mahā-Viṣṇu said:] I brought the brāhmaṇa’s sons here because I wanted to see the two of you, My expansions, who have descended to the earth to save the principles of religion. As soon as you finish killing the demons who burden the earth, quickly come back here to Me.
Purport: 

As explained by Śrīla Viśvanātha Cakravartī, the secret import of these words spoken for Arjuna’s edification is as follows: “You two, who have descended along with your kalās, your personal energies, should kindly return to Me after killing the demons who burden the earth. Please quickly send these demons here to Me for the sake of their liberation.” It is stated in Śrī Hari-vaṁśa and in the Second Canto of Śrīmad-Bhāgavatam that the path of gradual liberation passes through the intermediate station of Lord Mahā-Viṣṇu’s abode, outside the eighth shell of the universe.
