How many such Vaikuntas are there in the spiritual world? What is the authentic source in which such vaikuntas are described.
In my opinion, what Sanat Kumaras did was not commensurate with their Brahminhood position. A brahmin should never get angry even if provoked, that too, in Vaikunta (whatever be the variety). They did an act (act of anger and cursing) which is not acceptable in a saintly place llke Vaikunta. (i) The curse of Sanatkumaras and (ii) betrayal of his own servants, who were doing their duty only, by Lord Vishnu are NOT CORRECT.
Imagine how much pain and sufferings Jaya Vijaya would have undergone an IAS Officer to the post of Peon. That too, it is the price paid for doing their duty.
Imagine you are owning a palatial house. Some unknown persons visit your house without any appointment. On outward appearance, they look like persons who are not fit to enter such a palatial house. What will the gate-keeper do? Naturally, he will refuse entry for such visitors. What will the visitor do? Visitors, if they really know the Yajaman of the palatial house, will contact the Yajaman of that palatial house and express their grievance that they are prevented at the gate. Then, Yajaman will apprise the gate-keeper of the importance of those visitors and tell him to allow them to come inside OR would tell that he did not know such persons and not to allow those visitors. This is the natural course of action in such a situation. If such an amicable event had happened in Jaya-Vijaya story also, many innocent jeevas would not have undergone tortures.
Such a cruel act (of curse by Sanata Kumaras and recognition of it by Lord Vishnu) made uncountable Satva Guna Jeevaatmas suffer at the hands of HH, RK and SD. Sanatkumaras and Lord Mahavishnu are only responsible and accountable for such sufferings. The spiritual speakers always try to find some justification for such acts, which none can comprehend or justify; instead of accepting their ignorance that “I also don’t know; but it is a matter of belief based on our conditioned life since childhood”. Probably, such acceptance of “I also don’t know” will make them fall from their higher position than their audience.
