We exist in a field of thought. When this field operates in one direction while I operate in another direction, the difference between the pathways, my error and its degree, are perceived as the degree of my suffering.
The bigger the error, the bigger the suffering. Everything depends on how opposite the direction of my desires are to the program of creation.
How do I test myself in relation to the program of creation? I have the group for this. When I cancel myself in relation to the group, in other words, when I bring my desire closer to the program of creation, I begin to move according to this program and then I feel good, suffering cannot affect me because the source of all the suffering is our lack of correspondence to the program of creation.
