Traversing as they do all of Eurasia, the Silk Roads encompassed almost every climate and vegetation zone and crossed every kind of terrain. This sketch of Silk Road geography has the modest aim of introducing a few of the important features of Eurasian physical geography which help us to understand patterns of human habitation and interaction across that vast expanse. There are always regional variations which deserve more detailed treatment. Before the advent of modern technology, geography and ecological zones were critical determinants of where and how people lived, moved and interacted. Boundaries such as we know them, delineated by modern states, did not exist, but boundaries there were, either natural or manmade, and in both cases they turn out to have been quite permeable.
Regulations need to be followed from both states and the federal government.
Each state can set regulations because business is happening in each state. You would also need to follow federal regulation because you are crossing state lines to conduct business.
The federal regulations are typically fewer in number and scope but would create general guidelines for running the business. Due to federal power being superior to state power, all federal regulations would take priority over the state regulations. The states could each regulate business in addition to the federal regulations. Therefore state regulations tend to be more precise.
Alfred T. Mahan supported the building of a strong navy because they wanted "China to protect shipping lanes."
The Pharisees' legalistic approach led them to creating an ever-more complex system of rules, and their extra-dutiful observance of law focused on external obedience to rules more than internal attitudes of the heart.
Jewish rabbinical tradition counted 613 commands stipulated in the Law given to Israel by Moses. For the Pharisees (meaning "those who are set apart"), that wasn't enough. They sought to set themselves apart from the common man by the way they applied the Law to every detail of their lives, making their own specific rules for specific situations. So as new situations arose, new religious rules were imposed. The Pharisees' body of law was something like the US tax code in that way! They gave particular focus to all the ways that one should obey the rule of resting on the Sabbath.
In the process, the Pharisees also paid primary attention to outward adherence to rules. The spirit of the Law as originally given was aimed at conforming persons' hearts to the ways of God. But following the laws of the Pharisees became more focused on maintaining outward consistency with the rituals and regulations they had established. In regard to the Sabbath, the original intent was so that people would stop other activities in order to give full attention to God and his Word. For the Pharisees, the focus of the Sabbath became more about regulating how much activity was considered allowable or not in different situations.
