Sri Nrsimhadeva Bhagavan Ki Jaya!!!
In a previous age, so long ago in Satya-yuga, this incident happened. At that time, the munis and the rishis could go everywhere. Four such rishis were known as the Chatursana, the Four Kumaras: Sanaka, Sanandana, Sanatana and Sanata Kumara. The four of them went to see Lord Visnu in Vaikuntha Dham.
The gate-keepers of Vaikuntha were Jaya and Vijaya.
Upon arriving Jaya and Vijaya told them, "Now Lord Visnu is resting with Laksmidevi. Take seat and later we shall arrange for you to see Him." The four rishis were very disappointed and said, "It is Vaikuntha Dham. When we come here we have a right to go and see Lord Visnu. He is also ready to give his darsan (audience), otherwise why has He given us entrance to Vaikuntha Dham? We think there is no obstacle for us to see Him. Don't stop us like this."
But Jaya and Vijaya said, "It is our duty, sir, what shall we do." Then the rishis were very angry and said, "You are behaving with us like demons, then go to martya-dham, the material world, and take birth there as demons in the plane of death." Then in the meantime, Visnu, who knows everything, came out. When the rishis gave that curse, Visnu said, "Tathastu." Tathastu means, "What you said, that will be." And when this divine vibration came out from Visnu's mouth, the rishis were very surprised and Jaya and Vijaya were very disappointed.
They said, "Prabhu, You engaged us here as Your gate-keepers."
Visnu said, "Yes, it is My wish, otherwise the rishis would not curse you."
"Your wish?"
"Yes, I want to fight. My muscles are 'crunching', then I need to fight, to get some exercise, and with whom I shall fight?
You are the perfect fighters against Me. Then you go, and I shall go for saving My devotee. It is necessary to create some situation there. You will be My devotee's father and uncle, no problem." Then they were very unhappy and said, "Prabhu, we want to come back to our duty immediately. Give that opportunity to us."
And Bhagavan Visnu said, "Yes, if you come immediately, then you will be My enemy there. And if you come a little later, by seven births, you will be My friend. What do you want?"
They said, "By Your wish we are going, then we want to come back quickly. So maybe we will be Your enemy, no problem."
Visnu said, "That is My desire, otherwise why will you fight with Me?"
Jaya and Vijaya: the two gatekeepers of V a i k u n t h h a who were cursed because of having committed an offense towards the four K u m â r a R i s h i s, and therefore were condemned to be reborn three times in the material world as the great demons H i r a n y a k a s' i p u and H i r a n y â k s h a, R â v a n a and Kumbhakarna and S' i s' u p â l a and D a n t a v a k r a (see S.B. 7.1: 36-47).
