Two specialists in consultation, and then do as they rule — but the irreversible only after all else is exhausted. The Rebbe refused a lobotomy as “a partial murder of the soul,” told patients not to study their own case (“it breeds melancholy”), and in his last years drew a warmer figure: the doctor who is also a friend. Hands for medicine, mind for Torah.
Where people expect either "trust G-d, skip the doctors" or "just follow the doctors," he holds both legs in their proper roles. Medicine is a natural vessel one is obligated to use — the Torah "gave the doctor permission to heal" — approached with a working clinician's caution: two experts, the reversible before the irreversible, and a granular eye for the halacha a physician would never think to ask about.
The recurring directives, by how often each surfaces across the 285 letters.
The grounding phrase, again and again: התורה נתנה רשות לרופא לרפאות — "the Torah gave the doctor permission to heal." Using a good doctor is not a lapse of faith; it is the faith, made into a vessel.
He reasons like a careful physician who is also a posek: defer to the expert, prefer the reversible, guard against the cut that cannot be undone — and never let the natural vessel stand without the spiritual one beside it. Here, verbatim.
