On the Writing of a Torah Scroll:
Question
Answer
Hello
1. Hand work is more preferable.
2. To fulfill the mitzvah of writing a Torah scroll in the most enhanced way, one should appoint the scribe before the writing begins, or at least before the proofreading, and not purchase a ready-made Torah scroll. Even if the scroll is of the highest quality and can be read from immediately.
3. One can be an agent for a mitzvah, even if the person is unaware. It is considered a merit for him without his knowledge.
4. This does not diminish the mitzvah of the writer.
