In light of this preface, needless to say, the Tanya pertains and relates to every Jew, and, moreover, it is "near" (comprehensible), and, indeed, highly conducive to actual implementation in the daily life.
However, G-d has given everyone free choice of action, and it is His desire that the choice be made in the right direction out of one’s own free will. Yet, while presenting this freedom of choice, G-d gives the assurance that "it is near unto you," not only In word and thought, but also in actual deed. This is what the author explains in his book, where he also provides guidelines to the desired goal. He also explains why it is certain that every Jew will attain it, sooner or later, except that for one the road may be longer, and for another - shorter.
Inasmuch as you state in your letter that you are a professor of Pedagogic Sciences, it is confidently hoped that you will study the Tanya without prejudice, and then you will see the truth of the author’s ideas. Thus you will find it rewarding and beneficial not only for yourself, but - being a teacher and educator - you will want to share it with others. This is an additional factor that will contribute to the success of your said study, that will help "shorten the road."
I would like to add a further point. Where one has the opportunity and ability to influence others in the right direction, the time element is of the essence. For, with regard to one’s self, a person may think that he will make up tomorrow what he misses today; but with regard to another person one cannot be sure that the other person may be reached tomorrow, or that he will be as receptive tomorrow as today.
With reference to a Beracha, it is customary to remember one in prayer by mentioning the full Hebrew name together with the mother’s Hebrew name. If you will let me know these names, I will remember you in prayer for G-d’s blessing in all your needs.
At this time before Rosh Hashanah, I extend to you and yours best wishes for a happy and pleasant year, materially and spiritually.
With blessing,
M. Schneerson
