Prabhupāda: There is no need of so-called material science—how to kill children in the womb. These things will be kicked out. Nonsense.
Rāmeśvara: Do you think that they will adopt Indian medicine over Western medicine, things like that? Because there has to be some varṇāśrama.
Prabhupāda: No, medicine, if it is actually medicine, it will be accepted. It doesn't matter whether it is Indian or Western. If it is medicine it will be accepted.
Rāmeśvara: So that kind of research is in the mode of goodness.
Prabhupāda: That is already there. We have to make little research. It, already there. There are books, Āyurvedic books. They are very nice. Everything can be done. Dhanvantari. It is given by Dhanvantari avatāra, incarnation of Kṛṣṇa.
Rāmeśvara: You have written in the First Canto that we welcome scientists, doctors...
Prabhupāda: Yes, if it is beneficial.
Rāmeśvara: We welcome all these people if they dovetail their work for Kṛṣṇa.
Prabhupāda: Yes.
Rāmeśvara: So it's not that these...
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.
