Jurisprudence ke Basic Premise Mein Confusion

Maine kuch din pehle Jurisprudence ki baat karte hue, sir keh rahe the ki law ka origin kya hai ussmein kya baat hai. To kuch din pehle, kisi aur topic mein, professor keh rahe the ki law ke origin ko natural law se connect karna chahiye. Ab main confused ho gaya, natural law kon si cheez hai aur kaise voh law ka origin hota hai? Sir keh rahe the ki law ek man-manit system hai aur voh society mein apna presence rakhta hai. Lekin kya natural law ka role vohi hai? Maine kaha, sir natural law kya hai? Uske baad kaha, natural law uss law se connect hota hai jo society mein natural tarike se banata hai.
