Srila Prabhupada said that the demons those Krishna killed did not achieve Vaikunthaloka/ Gokul Vrindavan but a place in brahmajyoti.
Now, the 2 demons(previous gatekeepers of vaikunthloka) who were cursed by 4 kumaras were killed by Krishna and his expansions, should achieve brahmajyoti. But krsna says one who goes to spiritual world never falls down. If these 2 gatekeepers went to brahmajyoti then they can be considered as fallen down & krsna's statement would be false which cannot be true. On the other hand, per Srila Prabhupada, demons go to brahmajyoti only.
My understanding is that Jaya & Vijaya must have gone back to Vaikunthaloka only and not to brahmajyoti.
Please your comments or correct me.
