Pure unalloyed devotion to Krishna, without desire for liberation or reward, guarantees eternal service in the spiritual kingdom.Listen — Srila Prabhupada Uvaca
Prabhupāda: puruṣaḥ sa paraḥ pārtha bhaktyā labhyas tv ananyayā yasyāntaḥ-sthāni bhūtāni yena sarvam idaṃ tatam [Bg 8.22] [The Supreme Personality of Godhead, who is greater than all, is attainable by unalloyed devotion. Although He is present in His abode, He is all-pervading, and everything is situated within Him.] We have been discussing about the transcendental world. The transcendental world is above this material sky. The material sky is also a part of the transcendental sky, or spiritual sky—it is covered only.
This thing we have already explained. Just like the sky, some part of the sky is covered by cloud. The cloud cannot cover the whole sky. That is not possible.
That is not in the power of the cloud. Only insignificant portion of the cloud, er, sky, is covered by cloud. Similarly, the unlimited sky, spiritual sky, and some portion of it, when it is covered by mahat-tattva, or a spiritual cloud, the portion which is covered, it is called material sky. This material sky is meant for the conditioned soul.
Just like the prison house. What is this prison house? The prison house is a certain area of the state, walled, all side walled and protected, so that the prisoners may not come out. That is called prison.
But it is within the state, within the city, under insignificant portion. Similarly, this material manifestation is only a very insignificant portion of the spiritual sky, and it is covered so that we may not go to the spiritual sky. That is not possible. We cannot go.
We cannot travel even in the outer space of this material sky. So we have got very limited potency. But this is the situation. So there, in the spiritual sky, there are spiritual planets, and on each planet the Lord is manifested. There are innumerable planets.
So here it is, that information is given in the Bhagavad-gītā, that puruṣaḥ sa paraḥ pārtha: "That spiritual sky, the predominating Personality of Godhead is transcendental." Just like here, in every country, in every planet, there is a predominating personality. In your country, the predominating personality is President Johnson. Similarly, in every country there is a predominating personality. Similarly, every planet there is a predominating personality. So the same system is there also.
