Rocket, rocket. You have got very nice rocket, running at the speed of eighteen thousand miles or twenty-five thousand miles per hour. But you may go. If you don't take . . . if you don't get shelter in some planet—just as they're going in the moon planet, but do not get shelter and come back—similarly, supposing they are getting shelter, but that shelter is not very secure; they again come back.

Prabhupāda: In our Brahmā . . . Vaiṣṇava sannyāsa, there is little leniency. Because they live in Kṛṣṇa, so there is no need of very strict, rigid following. Although it is stated that they should live like this. But there is leniency. But Māyāvāda, they are very rigid in their principles of sannyāsa life. That is called āruhya kṛcchreṇa. Kṛcchreṇa, with great difficulty, they merge into the Brahman effulgence. Āruhya kṛcchreṇa paraṁ padam (SB 10.2.32). They attain the perfectional stage. Not perfectional, paraṁ padam, in the spiritual realm. But patanty adhaḥ: again falls down. Again falls down means because in the effulgence there is no varieties. The example is just like you have got a nice sputnik or, what is called . . .? Indian man: Apollo. Apollo.

Prabhupāda: No, no. By which they go?

Indians and Devotees: Rocket.

Prabhupāda: Rocket, rocket. You have got very nice rocket, running at the speed of eighteen thousand miles or twenty-five thousand miles per hour. But you may go. If you don't take . . . if you don't get shelter in some planet—just as they're going in the moon planet, but do not get shelter and come back—similarly, supposing they are getting shelter, but that shelter is not very secure; they again come back. So without shelter, how long you can fly in the sky? The sky is unlimited. You can fly on your sputnik or capsule, but if you don't get the shelter in some planet, then again you come back to your place.

So this is . . . the same example is given in the Bhāgavata: āruhya kṛcchreṇa, with great scientific method you can go up. But if you don't get a shelter, then you come back again on this planet. Similarly, the nondevotees, the impersonalist, they undergo severe penances and austerities undoubtedly, and they rise up to the brahma-jyotir. Āruhya kṛcchreṇa paraṁ padaṁ tataḥ patanty adhaḥ (SB 10.2.32). From there, he again falls down. Same example. Why? Anādhṛta-yuṣmad-aṅghrayaḥ. Because they did not care for the shelter under the lotus feet of Kṛṣṇa, therefore they have to come back again to this material world.
