Yeshiva guy says over a vort

according to Chassidus the avos performed all the mitvzos but in a spiritual manner. every mitzva that we do brings down a certain G-dly light. The Avos being on a grand spiritual standing knew which mitzva brings down what kind of hamshaha so they were able to bring down those lights in their own way. they didn't do all the mitvos like we do them with physical objects but they did accomplish the same ends so you can say that the Avos kept all the mitvos even before they were given. One example is when Yacov used the striped sticks, it is explained that at that time he accomplished the mitva of teffilin. These are my thoughts on the matter, hope it helps more than confuses. lol.:)
