All our advancement is determined by the sensitivity of our desire, or the amount of qualities it discerns. Increasing one’s desire does not mean making it bigger. The development of the desire is qualitative, not quantitative.
When we prepare for entering the spiritual world, we have to focus on the quantity of the impressions we have accumulated, because their quantity determines the quality of our desire. The most important thing about the desire isn’t its size, but its direction, sensitivity, and focus on the goal, on “what do I consider the most important thing?” Therefore, our task is to focus on making our desire correct, and when it becomes correct, the fulfillment will immediately be revealed inside it.
So, the most important thing is to acquire the full degree of desire, to accumulate the appetite for the feast that the Creator has prepared for us. There is a royal feast waiting for us, and a world full of goodness. As soon as our desire will match the fulfillment, we will immediately feel the fulfillment inside us. It already fills us, but it is concealed and operates inside the Kli.
