The prayer is called work in the heart because the mind resists it and I have to go against it. That is, I ask the Creator for something that my whole nature resists; therefore each prayer requires special work in the heart because I want to go against my mind and reason, which prove the opposite to me.
However, I do not want to understand with my mind that it is worth working for the Creator. I want to work only with faith above reason.
It is interesting how it works because I feel that everything within me is resisting: I do not want connection, study, altruistic actions, dissemination, and connection with friends. I do not want to use any means that can bring me closer to the Creator.
This inner resistance becomes more and more explicit every day, but each time I have to act in exactly the opposite way. I see this reluctance within me and know exactly where it is in my egoism, but on the outside, I must do the exact opposite.
There is nothing that attracts me to this and obligates me, no one is forcing me, but I myself try to find the strength to do something for the sake of bestowal above my reason. This is how the transition from reason to above reason, above desire occurs. This is the transition from the corporeal world to the spiritual world. The entire spiritual world is built above reason, above my normal desire.
