Every soul has its nature, and if one tries to bury it, although it will remain covered for some time, it only needs digging; anyone can dig and find what is beneath. There may be a good nature hidden, and there may be a bad nature hidden, though for the moment one does not see it. A soul may seem to be a saint until one has spoken with him; another soul may seem to be quite the contrary until one has investigated him, and then he may prove to be totally different.
