Esoteric Lesson
When you sit down to meditate, you should make sure that the room is neither too warm nor too cold, so that you feel as few physical obstacles as possible. The first thing that will occur is a kind of inner restlessness, as if something were stinging and crawling in our blood, so that we feel distracted; yes, it can even become a rushing of the blood. Those who have not experienced this may think that they are better at meditating. But this is not the case, because everyone must experience this tingling in the blood to a greater or lesser extent, and it is proof that you are on the right path, because it brings something to our consciousness that we tend to overlook in everyday life. The stinging and tingling of the blood makes us aware of the egoism with which we are still afflicted and which prevents us from entering the spiritual world. At first, this will prevent us from acquiring the necessary calm, but if we continue meditating vigorously, we will reach a point where this tingling, while still present, will no longer disturb us.
