The word “Klal” (collective/rule) indicates a sum of details that, when put together, form the above collective. Thus, when he says about the Mitzva, “love thy friend as thyself,” that it is a great Klal in the Torah, we must understand that the rest of the 612 Mitzvot (precepts) in the Torah, with all their interpretations, are no more and no less than the sum of the details inserted and contained in that single Mitzva (singular for Mitzvot), “love thy friend as thyself. (Baal HaSulam, “Matan Torah” – “The Giving of the Torah”).
This means that the entire Torah is given in order to attain the general rule of loving our neighbors as ourselves. The rest that is written in the Torah except this one concept “Love thy neighbor as thyself” is just a clarification of this rule.
Everything is included in this one rule. That’s why when we forget this rule, no spiritual path is possible for us, nor are we connected with the spiritual process or continue pursuing the spiritual goals any longer. If we attempt encompassing this principle, we can even stop checking the level we are at or trying to find out where we actually are.
The whole Torah was given to us and is meant to help us to attain connection that is called love in our lives. There are two ways of doing it: One is by following a long road full of affliction that represents the natural developmental way, and the other is a pleasant shortcut that is ensured by the Torah. One way or the other, the entire humanity, from the very beginning to the very end, is engaged in advancement that leads us to loving our neighbors.
If we understand and acknowledge that we are now just practicing and playing games, we follow a relatively easy and comfortable way of reaching the goal. Still, we’ll have to go through some troubles and problems, resolve and explore them so that we get a better feeling of their essence and origin. We will have to resolve various situations in our minds and sensations because this process lets us to better understand and feel things.
In order to make this path easier and more pleasant for us, there is the Torah with the help of which we reach the state of loving our neighbors. From this phase on, we eventually will come to loving the Creator. However, there is nothing we can achieve by just following the path of suffering. Everything depends on the awakening on our side.
