Silk was - and still is - a very expensive material; controlling knowledge the process by which silk cloth is made allows you to be the only producer of silk and name your own price. Once it becomes common knowledge, anyone can make it and under-cut your price.
Hell's best kept secret is the true power of redemption. This secret is closely guarded because it goes against the narrative of eternal punishment and suffering in Hell, offering hope and a chance for change to those who may have been deemed irredeemable.

In basketball, a player who is closely guarded (within six feet) has a maximum of five seconds to either pass, shoot, or dribble the ball. If the player does not do so within this time frame, a violation is called, resulting in a turnover to the opposing team. This rule is designed to encourage movement and prevent stalling.
The maps and charts from Prince Henry School were likely guarded closely due to their valuable and sensitive nature, as they contained critical navigational information that could provide significant advantages in exploration and trade. During the Age of Discovery, such knowledge was a key asset for maritime nations, and safeguarding it would have been crucial to maintaining economic and strategic dominance. Additionally, the competitive nature of exploration during that period would have heightened the need for secrecy to prevent rival nations from gaining access to these insights.
It was guarded night and day.
Patents and trade secrets are both ways to protect inventions, but are otherwise very different. A patent is formally registered with the federal government, and the information is available to everyone ("patent" in this instance means "open"), but the inventor has the right to prevent anyone from using it without permission. Patents are normally good for 20 years. A trade secret is not registered or revealed to anyone, and can be protected forever--or until someone figures it out by reverse-engineering or other means. So if you patent your new widget, I can look at the plans and specifications but I can't do anything with them without your permission, for 20 years. But if you call your new widget a trade secret and I figure it out the following week, that's it: no more secret. That's why trade secrets are almost ridiculously closely guarded.

The secret of silk-making was closely guarded because silk was a highly valuable commodity in ancient times, primarily sought after for its luxurious texture and vibrant colors. Controlling its production allowed China to maintain a significant economic advantage and foster trade along the Silk Road. The Chinese government imposed severe penalties for anyone who attempted to reveal the silk-making process, ensuring that their monopoly on this prized fabric remained intact for centuries. This secrecy not only protected their economy but also contributed to the mystique and allure of silk in global markets.
