If you perform actions directed toward the goal of creation, you advance with the help of two forces: your own desire and the Light. But if you perform actions that aren’t directed toward the goal of creation, you advance only with the help of one force: your desire. Developing naturally, we fulfill our own needs.
All of reality is essentially desire and the Light. Desire exists within the Light and is constantly changing, more and more. This is the way our natural development is carried out: from a point of energy to matter that becomes increasingly complex, until the present form of life. There are basic elements that create the cyclical system, and there exist connections between them that produce complex materials and even living cells that absorb and discharge all kinds of substances. The cells consist of a new, qualitative connection with the environment because at the still level, the absorption and discharge don’t produce the sensation of life or pain.
Thus, if we want to advance forward, we face a special condition: either to advance under the influence of nature’s force, like a machine, or to create a connection with friends in the group and to build a model that is essentially similar to the Light, the upper force, love and bestowal. You overcome the heaviness and the problems, and accordingly you receive help from Above. In principle, you don’t activate anything new, but in your wanting to advance to the goal, you add your efforts, and in response to it, you receive extra Light from the state you long for.
In the end, you use the same system that responds to “the addition” from our side. If you want it, go ahead, and if you don’t, then you don’t. The changes don’t come from the Light, but from you: If you invested efforts, showed more desire, then you discover an addition of deficiency on your side, and then you receive a greater illumination. No one Above makes decisions about allocating you a portion of the Light. The Light is at absolute rest, and everything depends only on your need for it. Take advantage of the conditions given to you—and you will receive it.
