I am in love with a BK and I have been following this forum for some times. First of all, one has to understand that whatever the BK leadership is calling their teaching it's not "spiritual".
Second thing is that those people who are followers of BK thinks it's a Hindu Sect ... but that's not true. The BKs have adopted Hindu principles of self control and meditation to their own agenda.
(I am telling in context of love) It's thought that it's impossible to get a BK to love you in the manner us non-bk expect. That may be true because the BKs have been conditioned to not to listen to anyone else, to shut their self from outer world.
Now the reason a BK acts like these may be various; but one fundamental common ground here is that most of BK who are conditioned this way (NOT ACKNOWLEDGING LOVE FOR A NON-BK; NOT COMMITTING IN RELATIONSHIP, NOT HAVING SEXUAL RELATIONS) were suffering from an acute "mental breakdown". These mental breakdowns led them to question their existence. Their purpose to live was not there. They are not accepting the reality which caused the circumstances which lead to the "mental breakdown".
Further more, in some cases they are not accepting that what caused such a trauma and "mental agony" was consequences of decision they made and steps they have taken. (Here some case could be that the situations was really out of reach of anyone that caused the "mental agony"). IN A WAY, THEY WANT TO ESCAPE REALITY.
So they want an escape route that relives them of the burden. Now BK comes in play with their soul theory (which isolates them from situation at hand); karma theory (Wwich blames the doing of the same soul in some other life for the "situations that caused the mental agony") {{ how ironic }}. With these two theory an inception of god who is "capable" of cutting karmic debt is planted in their minds.
Now these two things works like a drug (highly addictive drug) to the new comer to BK. How to counter this effect caused by BKs? One has to understand fully what ever caused one's loved one to be dragged in the cult. It would be different from case to case. And consult a good psychiatrist (for your self and your loved one as well) telling the cause that dragged your loved one to this mess (start sessions without your partners). This will start making sense after some times and will prepare you for possible rejections you might face. (Showing true colors of BKs won't work, it has to be seen by the person in BK clutches )).
Of course, leaving your loved ones could be an option too but (love too acts like an highly addictive drug), so don't lose heart and believe in fate (NOT DRAMA) but fate, and believe in all mighty GOD [To be precise the rules which GOD made] who CREATED us, this earth, other animals, plants, the elements, our solar systems, our Galaxy and so much more things in the vast universe. (THAT their - BKs - f**ing god is not capable of comprehending).
Try to fill them (your loved one in BK ) with Guilt. (Yes, it's a dirty cheap trick) but all's in love and war, and what we are in is a superb mix of both. (HERE A CAUTION DON'T PUSH THE LIMIT WITH THE GUILT THING, DON'T ACKNOWLEDGE THEIR GUILT IF THEY TELL YOU.)
P.S.
(Beware RAJ Yoga is not the pillar for BKs it's a tool to affect one's mind.)) (It's bound to experience solitude, peace, power and divinity by sitting in peaceful silent room with music). Because there are no other inputs to the brain which requires critical brain computing power. So all the resources of our brain is diverted towards memory management and data correction. Now how does this happen, when ever the brain access the storage space it generates electronic signals which we knows as thoughts. And it's stored in permanent location or discarded out of system by their importance "decided by our own criteria")) now what happens when it finishes the memory management and data correction process. The electric signal stops or sub-sides gradually. And we know that state as "SPIRITUAL EXPERIENCE". And, by jove, it's not a BK copyright.
