In response to your letter in which you write of the possibility of extracting energy from various sources in order to create electricity in a seamless fashion, I share the following:

First, you would do well to consult experts in the field. Since, however, everything in life is by Divine providence, including your correspondence with me on this matter, please allow me the opportunity to draw a spiritual lesson from this process.

In simple and spiritual terms: One is to strive to extract the hidden potential found in one’s fellow Jew, the children of our Patriarchs and Matriarchs, so that one’s fellow can actualize his essence. Although the material aspect of one’s life is more pronounced in man, one is able to extract and reveal the inner essence within him to the point of reaching his soul. One is to be assured that all this can be accomplished, in your words, in a seamless and simple manner by way of “Words that come from the heart, enter the heart.”
