Rav Kook deals here with 3 common spiritual problems: over-indulging in physical pleasure; "under-indulging"- going to the opposite extreme & how fasting and ascetic life is counter-productive for the modern man; & superstition. Rav Kook's unique approach to superstition & the passages in the Talmud which seem as such stress that we must rise above the nature to fear and "quake" regarding topics beyond human control. Rather than imagining superstitious acts, which help us feel in control of the uncontrollable, we should connect with He Who is in total control and His Torah wisdom. HaRav doesn't contradict those rabbinic passages, but says they're secondary & better off not worrying about. Only he who worries about them has what to worry about.
If someone asks me for an answer during a test, can I tell him the wrong answer? (Response to follow-up question – I prefer not to refuse either to not suffer socially or so the cheater gets what he deserves.)
A person must maintain total integrity in all his dealings – after all, we are
commanded to act like Hashem in all our deeds, and Hashem’s seal is truth (Shabbos
55a). Furthermore, someone who is meticulously honest and truthful will merit
receiving the Presence of the Shechinah.
