There is a rule: “if you leave Me one day I shall leave you for two.” This is similar to the rule of “to reveal a portion and conceal two”… it is a preliminary condition for the creation of the vessel.
A person is intentionally given the option to fail, which is called “if you leave Me one day,” and then he has to work to correct himself for two days. This means that he leaves the level he was on, falls, and sins. But he falls to an even lower level: not to the egoistic level that is the inverse of the level of bestowal he had reached, but to an even lower level. Not to minus one (-1), but to minus two (-2), and then he has to ascend to the second level, to plus two (+2).
When he finally arrives to +2, he falls to -3, and then he has to rise to +3. We progress in this way; all these actions benefit our advancement. When we fall, we have to work twice as hard.
The main thing is not to lose the persistence, not to stand still because you see that you are not getting any reward. Each time we need to find greater reward that is more and more detached from corporeal life. We should learn to measure the reward in relation to the common good: to what extent can I work and the others receive.
I have to make efforts that the reforming Light will bring me closer to this attitude in which I will receive more and more fuel to work for the benefit of all the others and not my own. This is how my advancement is measured.
