By the Grace of G‑d
19 Adar-Sheni, 5711 [March 27, 1951]
Brooklyn, N.Y.

Greeting and blessing:

….The Torah is the Truth. Therefore, there can be no other truth which is in conflict with it. It follows that anything which is in conflict with the Torah is not Truth. The purpose of science is to discover Truth. Therefore, any study which contradicts the Torah is not science but the opposite of it, and instead of leading the student to the truth, leads him away from it. Moreover, even where the science which one studies corresponds with the truth, there is no assurance that it will be applied to constructive purposes and not for the destruction of self and others, unless it is guided by the Divine truth of the Torah. Only then will the world become — as G‑d intended it to be — a Sanctuary for the Divine Presence, that G‑d may be manifested in it and in ourselves.
