Levels of prohibition on Shabbat
Question
Answer
Shalom u’vracha
First: with any melachah that a person refrains from doing on Shabbat, they thereby fulfill a mitzvah from the Torah and avoid a severe transgression.
In this respect, it makes no difference from which particular melachah they refrained.
Second: there are things such that, as soon as one refrains from them, one thereby avoids a great many melachot. Thus, the benefit of that self‑control is especially great.
For example, when travelling in a car with a fuel engine (not electric), every minute of driving includes hundreds of ignitions of fire. Therefore, refraining from travelling means “saving” oneself from thousands of Torah‑level prohibitions.
Smoking a single cigarette involves dozens of ignitions, whereas turning on a light involves only one ignition.
Cooking a meal sometimes includes many melachot, such as kindling a fire for cooking, boiling water, cooking the dish itself, mixing ingredients which is sometimes considered “kneading”, cutting vegetables in a way that is considered “grinding”, and operating various appliances, which in themselves include many melachot.
And of course, in light of this, it is worthwhile to begin with the biggest “landmines”, where with a single decision the gain is very great!
For example: cooking the Shabbat foods before Shabbat. Or: not smoking on Shabbat. And so on.
