The question is that Lord Vishnu knows everything. So did he not know that Rahu and Ketu were also pretending to be devatas? So why did he let them drink a little bit of the nectar and survive as heads? Actually, the Acharyas described that through Rahu and Ketu, the power of the nectar is demonstrated. That through Lord Shiva, the power of devotion and purity is demonstrated.
That even poison can’t have effect. But the power of nectar is demonstrated through Rahu and Ketu. That just the contact of nectar made their head survive forever.
And generally in his pastimes, the Lord sometimes manifests his omnipotence and sometimes does not manifest his omnipotence. So omnipotence means supreme power. And one aspect of the omnipotence is also omniscience.
He knows everything. Now when Krishna goes and searches for butter, he searches, he goes here and he goes there and searches for butter. Now he is all-knowing.
So he can just go and find the butter and eat it. But why does he search? Because in the search, there is a thrill, there is excitement and there is fun in that. And the Lord wants to enjoy that rasa.
So in his pastimes, sometimes to intensify the excitement and to give an opportunity for service to others, he sometimes covers his omniscience. So when Narada Muni comes and informs the Lord that actually the demons are creating a lot of trouble or he comes as a messenger about something. Narada Muni comes and tells that Yudhishthira wants to perform a sacrifice, Rajasurya.
And for that purpose, he has to arrange to win over all the kings. So he is thinking whether he should do it or not. Then Narada Muni himself says, actually my dear Lord, you know everything, but you are simply giving me some service.
So Krishna sometimes manifests and sometimes covers his omnipotence to intensify the pastime and to give opportunity for service to his devotees. And in this particular case, he allowed Rahu and Ketu to continue their pretense for some time so that through the relative immortality of their head, the power of the nectar could be demonstrated.
