229. So long as research still takes place in zones where the researcher can be supported by his physical senses and if these are inadequate can remedy the deficiency by the technical apparatus already mentioned so that as far as they reach he can obtain realistic physical experiences of facts to support his research, then he can very well be "eminent" and "distinguished" without a moral basis. In this case there is not so much demand made on his faculty of concentration in that he can actually hold the object being researched with the physical senses and with instruments or other aids, and the appropriation and utilization of these are not dependent on having any kind of moral basis. The immoral researcher will just as well be able to use a microscope or his own physical senses as the moral one. It is different when research is in zones where the physical senses and artificial aids cannot reach so far or be any support, and the observations are therefore based on the researcher's own individual mental faculty. Where this faculty does not reach he cannot remedy it with any type of apparatus or helpful aids. Here it will depend solely on the maturity of his spiritual bodies and thereby his faculty of concentration. As already mentioned, a perfect faculty of concentration depends upon absolute mental equilibrium and this can exist only on the basis of complete cleansing of desires or lower tendencies in the consciousness. So here we return to the eternal saying: "Blessed are the pure in heart, for they shall see God". Terrestrial mankind's science is now nearing that zone of evolution where its representatives can be eminent only through morality.
