Many times in these pages we have discussed the spiritual planets situated beyond the material sky, and the description is corroborated in this verse. The word sanatana is significant. This very idea of eternity is expressed in the Bhagavad-gita (8.20), where it is said that beyond the material creation is the spiritual sky, where everything is eternal. Sometimes Satyaloka, the planet in which Brahma resides, is also called Brahmaloka. But the Brahmaloka mentioned here is not the same as the Satyaloka planetary system. This Brahmaloka is eternal, whereas the Satyaloka planetary system is not eternal. And to distinguish between the two, the adjective sanatana has been used in this case. According to Srila Jiva Gosvami, this Brahmaloka is the loka or abode of Brahman, or the Supreme Lord. In the spiritual sky all the planets are as good as the Lord Himself. The Lord is all spirit, and His name, fame, glories, qualities, pastimes, etc., are all nondifferent from Him because He is absolute. As such, the planets in the kingdom of God are also nondifferent from Him. In those planets there is no difference between the body and the soul, nor is there any influence of time as we experience it in the material world. And in addition to there being no influence of time, the planets in, Brahmaloka, due to being spiritual, are never annihilated. All variegatedness in the spiritual planets is also one with the Lord, and therefore the Vedic aphorism ekam evadvitiyam is fully realized in that sanatana atmosphere of spiritual variegatedness. This material world is only a shadow phantasmagoria of the spiritual kingdom of the Lord, and because it is a shadow it is never eternal; the variegatedness in the material world of duality (spirit and matter) cannot be compared to that of the spiritual world. Because of a poor fund of knowledge, less intelligent persons sometimes mistake the conditions of the shadow world to be equivalent to those of the spiritual world, and thus they mistake the Lord and His pastimes in the material world to be one with the conditioned souls and their activities. The Lord condemns such less intelligent persons in the Bhagavad-gita (9.11):
