Likewise the soul will become interested in the external factor which promotes the action and which somehow serves as a means to fulfill the desire. In this state, we express love for such and such an act, object or person. The requirement of love is the incessant concern of the soul for the beloved and the performance of deeds harmonious with this concern.
So if we want to give a particular direction to our process (of development) and to mobilize all our powers for the attainment of a specific goal, we must strive for the persistence of the soul's concern for the objective and for its direction. We must do something, so that the soul would become acquainted with the objective and would develop strong love and affection for it.
Persistence of the soul's concern for and concentration on a single objective hinges on ignoring whatever is contrary to it and on abstaining from independently considering any other demand. The soul should employ all instincts at the service of its sublime and perfectionist demand and deem their satisfaction secondary to the fulfillment of this (main) demand.
