So at the present moment, we want to see God, but we do not acknowledge that we are not qualified. How we can see? If I cannot see even an ordinary president... By my whims I want to see the president or the such and such big officer. You cannot see unless you are qualified. So how you can see God? That is not possible. You have to qualify yourself. Then you will see God. Akṣi-gocaraḥ. Akṣi-gocaraḥ means, just we are seeing—you are seeing me, I am seeing you—similarly, you will see the demigods or God, provided you are qualified.
So Mahārāja Parīkṣit was so exalted king that by his invitation, the demigods would come and public could see. That was possible. That is stated here. He was so, I mean to say, exalted king, he could invite. And the kings also were invited. Just like Mahārāja Yudhiṣṭhira went. That was interplanetary exchange. That is now not... You cannot go by the sputniks to the heavenly planet. The moon planet is also one of the heavenly planet. Or the other planets. They are all heavenly planets. Ūrdhvam. Ūrdhvaṁ gacchanti sattva-sthāḥ (BG 14.18). When you are competent, fit, for going there, then you can go there. That is stated in the Bhagavad-gītā. Yānti deva-vratā devān pitṟn yānti pitṛ-vratāḥ, bhūtejyā yānti.. (BG 9.25). You can go, but you must be qualified, pitṛ-vratāḥ, deva-vratāḥ. Similarly, you can go to Kṛṣṇa also if you are kṛṣṇa-vratāḥ. Mad-yājino 'pi yānti mām. What to speak of going to other planets, if one is qualified, if one is pure devotee, Kṛṣṇa says, "He also comes to Me." So this exchange of going and coming is not difficult, provided a person is qualified. Not a cat and dog can go. That is not possible.
