Answer: This is the key, and if you succeed, you don’t need anything else. But I don’t know how to help here for this is exactly what is described by “Whatever is in your power, do it!”
No work is more important than preparation to the lesson. Dissemination and everything else you do in this world, everything must revolve around one point: to build an inner plea during the lesson, the anticipation of the Light that will descend and reform us.
This must become our obsessive thought, an internal ache, a feeling that without it I will die, and it will be even more frightening than to die in the corporeal world! It is impossible to arrive at such powerful desire on your own; a person needs the group, support, and collective inspiration. We need to feel despair which accumulates over the years of effort….
It is the most profound point around which everything revolves. If you reach it, you will succeed in everything. There is nothing more; this is the point where you connect with the Creator. Through it, from below upward, the prayer, MAN, is raised. His response, MAD, arrives through it from Above downward, for now as the Surrounding Light.
This need, the aching point, must stand out clearly and conspicuously as the most meaningful need. We need to constantly care for it and think how to enhance it, how to come to the studies with a broken heart so we may bond together during the lesson.
The rest is not important; what you know and what you’ve done does not matter at all. The final outcome of your entire life and all your effort is contained only here, in this point. If you come to it, you will attain everything; if not, nothing else is worthwhile.
Nothing else is taken into account but this point for only it is called the "human" within me. It determines whether I do exist or not.
