Prabhupāda: We do not approve anything which is not actually beneficial. Otherwise it doesn't matter, homeopathic or allopathic. But there is standard medicine given by Dhanvantari.
Rāmeśvara: Yes. But what about certain technological advancements like airplanes and automobiles?
Prabhupāda: There are subtler aeroplanes. Aeroplane is mentioned in the śāstras. Now they are working on machine, but there are aeroplanes which can work on mantra.
Rāmeśvara: But that science is lost.
Prabhupāda: Not lost. It is there.
Hari-śauri: It's hidden.
Rāmeśvara: We can't practice that.
Prabhupāda: No, we can practice what is called ākāśa paṭala. This book is there in Germany. It was purchased by the Germans.
Rāmeśvara: But do you think that the Vedic sciences will be revived as our movement becomes...
Prabhupāda: No, no, our main purpose is to revive Kṛṣṇa consciousness. In favor of this Kṛṣṇa consciousness, whatever is available, beneficial, we shall adopt.
Rāmeśvara: Yes.
Prabhupāda: That's all.
Rāmeśvara: In other words, we want to reorganize all of society so that they develop Kṛṣṇa consciousness.
Prabhupāda: Kṛṣṇa consciousness. That's it. We do not hate anything. That is not our business. Just like we utilizing this. So it is modern, scientific gift. So we can utilize it for spreading Kṛṣṇa consciousness. We do not say... We are not so bigot—"No, no. It is material. We shall not touch it." We are not such fool.
Hari-śauri: No, we can use everything.
Prabhupāda: Yes.
