SB 2.7.34-35, Translation and Purport

All demonic personalities like Pralamba, Dhenuka, Baka, Keśī, Ariṣṭa, Cāṇūra, Muṣṭika, Kuvalayāpīḍa elephant, Kaṁsa, Yavana, Narakāsura and Pauṇḍraka, great marshals like Sālva, Dvivida monkey and Balvala, Dantavakra, the seven bulls, Śambara, Vidūratha and Rukmī, as also great warriors like Kāmboja, Matsya, Kuru, Sṛñjaya and Kekaya, would all fight vigorously, either with the Lord Hari directly or with Him under His names of Baladeva, Arjuna, Bhīma, etc. And the demons, thus being killed, would attain either the impersonal brahmajyoti or His personal abode in the Vaikuṇṭha planets.

All manifestations, in both the material and spiritual worlds, are demonstrations of the different potencies of Lord Kṛṣṇa. The Personality of Godhead Baladeva is His immediate personal expansion, and Bhīma, Arjuna, etc., are His personal associates. The Lord would appear (and He does so whenever He appears) with all His associates and potencies. Therefore the rebellious souls, like the demons and demoniac men, mentioned by names like Pralamba, would be killed either by the Lord Himself or by His associates. All these affairs will be clearly explained in the Tenth Canto. But we should know well that all the above-mentioned living entities killed would attain salvation either by being merged in the brahmajyoti of the Lord or being allowed to enter into the abodes of the Lord called Vaikuṇṭhas. This has already been explained by Bhīṣmadeva (First Canto). All persons who participated in the Battlefield of Kurukṣetra or otherwise with the Lord or with Baladeva, etc., would benefit by attaining spiritual existence according to the situation of their minds at the time of death. Those who recognized the Lord would enter Vaikuṇṭha, and those who estimated the Lord as only a powerful being would attain salvation by merging into the spiritual existence of the impersonal brahmajyoti of the Lord. But every one of them would get release from material existence. Since such is the benefit of those who played with the Lord inimically, one can imagine what would be the position of those who devoutly served the Lord in transcendental relationship with Him.
