(From the book Shamati by Kabbalist Y. Ashlag)
The basic, primary principle is to increase the will, for that is the basis upon which the structure builds and the strength of the construction is measured by the strength of its foundation.
Many things compel one to labor, but they do not aim at the cause. Therefore the foundation impairs the whole of the building. Although from not for His name one comes to for His name, it still lengthens the time before one returns to course. Therefore the cause should always stay before one’s eyes. It says: “I see the Lord before me always”, and one who stays home is not like the one who stands before the king. He who believes in the reality of the Creator, who believes that the land is filled with His honor, such a man is filled with love and fear, and needs no preparations or observation, only to nullify oneself before the king, just as we see that he who truly loves his friend, thinks only the best for him and avoids anything that isn’t beneficial to his friend. All that is done without any thought, for it is as natural as a mother’s love for her child, who only wants to benefit her child and needs no prior thought for that, as no instinct needs a mind but is operated by the senses themselves. The senses themselves are naturally devoted, as due to the love of an object they give their heart and soul for it until they have attained their goal, else their life is not a life.
Thus whoever feels that he is in completeness, means that he has faith. And if one does not feel one stands before the king, than one is opposite to Him. Hence, one should first and foremost regard slavery, and one must regret not having sufficient faith, as will for faith is one’s foundation and one should pray for labor and desire to feel that want, for if one hasn’t this desire, one hasn’t the vessel to receive the filling. One must believe that the Creator hears our every prayer and that one will be salvaged too through comprehensive faith.
