I was propositioned in Madubhan once, by a Sister I had given the course to, "I am going to jump on you in a minute," she said ... Man, I quivered all the way to the shower
Omshanti. In order to avoid such situations, which may or may not be common in the BK centers, a set of rules have been framed for the PBKs. Generally, course is given to new BKs or non-BKs only by Sisters/mothers at the Gitapathshalas/mini-Madhubans/their homes. Brothers can give course to Brothers only. In such cities where there are no PBK Sisters/mothers, I think the concerned PBK Brother seeks the opinion of Baba before giving introduction or course to Sisters/mothers.
And whenever an unmarried surrendered/non-surrendered Sister gives the Advance Course/knowledge to any new BK/non-BK/PBK, a PBK mother also gives her company.
From a Western point of view these rules may appear to be a bit archaic/strict, but keeping in view the situation of the Iron-Aged world, these rules help in maintaining the level of purity/celibacy that the society expects from a religious group, leave alone the expectation of purity as per the Murlis/Avyakt Vanis. These rules remove the possibility of deterioration of thoughts/vibrations/vision on both sides (i.e. giver & seeker of knowledge) to a great extent, if not fully.
There are many BK centers where single or two BK surrendered and/or non-surrendered Sisters live. And even in the BK centers where more than two surrendered BKs live, it is generally observed that the BK Sisters give the course to Brothers/strangers alone. So, one can imagine the vibrations/visions that may be passed on by the strangers to the BK Sisters. Of course, one may contend that if one's spiritual stage is high, then no danger would be caused. But the pollution of vibrations under such free circumstances cause harm in the long run and those who have been associated with the BKs since a few decades can know the difference in the vibrations/stage of surrendered BK Sisters/Brothers then (a couple of decades ago) and now.
