There are many ways, indeed, to test with what spirits you are communicating. Anyone who wants to judge must, under all circumstances, take the trouble to study the vast subject of how to test spirits. Only then will that person be in a position to determine from where they come. I have spoken about this subject and will do so again in the future. For the time being, I only wish to say this: If you still lack the necessary knowledge to determine with what spirits you are communicating and what laws are involved, you can ask your heart right now. You will get the answer to some extent, provided you do not let your doubts shade your feelings. If your feelings are receptive and open, you will be able to find and feel harmony, as well as love, patience, wisdom, and humility—or the opposite of all this. But your heart will only be able to speak to you and confirm what you wish to know if you are receptive, if you are open and put all prejudice aside for the moment. (PL#22)
