My Answer: The ultimate help is when a person spends all the hours of his existence trying to think about correcting himself and the world.
After all, a breaking first occurred in the worlds and then in the common soul, and now the broken souls exist in a broken world. Correction is possible only by the method of Kabbalah, which helps us draw the Upper Light, which alters our intention from an egoistic one to a giving one. The same force, the same Light, which created the whole universe, needs to affect us and correct everything.
Therefore, we can help others only by disseminating the science of Kabbalah until we reach complete redemption. However, while the world still needs correction, we need to try to bring the correction to the world. During the Convention we received a great force from our mutual unification because, together, we attained greater understanding and sensation.
And now we need to perform immense actions for the sake of the general correction of ourselves and the world. We received advancement precisely for this purpose and no other. None of us would have received what we received (an opportunity to participate in this gathering, an understanding of something, or feelings) if we were unable to affect the world through our correction.
