What is material science? We cannot go even to this moon planet, what to speak of the spiritual planet. It is not possible. It is not possible. So avyakto 'kṣara ity uktas tam āhuḥ paramāṁ gatim. That is the . . . if we want to penetrate the outer space, we should be able to penetrate this outer space, or this covering, then enter into that spiritual sky, and there it is called paramāṁ gatim. That sort of journey is called supreme. Not that you go up 25,000 away from this planet and again come back. This is not very heroism. Oh, you should have to penetrate the whole material space and then penetrate the cover and then reach the real sky. Yes.
And that information is here also in the Bhagavad-gītā. Paramāṁ gatim. That is the superior journey. That you cannot do with your tiny Sputniks. It is not possible. That you have to do by Kṛṣṇa consciousness. Tadā . . . sadā tad-bhāva-bhāvitaḥ (BG 8.6).
One who always absorbed in Kṛṣṇa consciousness, and if by fortune at the time of death he thinks of Kṛṣṇa, he is at once transferred within a second. That is the process. Therefore if we at all want to go that spiritual sky, and attain real life, eternal life, blissful life, and full of knowledge, sac-cid-ānanda-vigrahaḥ . . . Īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ [Bs 5.1].
The Lord has got this body, sac-cid-ānanda-vigrahaḥ. We have also that sort of body, but it is very small. Now it is covered by this matter, by this dress, and if we some way or other able to give up this false dress, then we reach that spiritual kingdom, God's kingdom. That is paramāṁ gatim. Yaṁ prāpya: "If you can reach there, if you can achieve that perfection," yaṁ prāpya na nivartante, "if at once you go, you cannot . . . no more to come back. No more to come back." Yaṁ prāpya na nivartante tad dhāma paramaṁ mama: "That is My superior abode."
So everyone should try to go there. God Himself comes to call you, He sends His son to call you, and the literatures are there, the scriptures are there. We should take advantage of this. This is meant for human body, human life, not for the cats and dogs. So we should take advantage of it. Human life is meant for that achievement. Then we finish all this trouble. This trouble of repeating birth and death, the cycle of birth and death, this should be stopped. This is the information of Bhagavad-gītā. This is the perfection.
