BK theory of karma is false.
The problem of the Raja Yoga theory of karma is that it is enclosed within the 5000 year cycle. So far, no one is able to explain clearly how negative karma creeps into the entire cycle, since everything was perfect at the beginning. The closest explanation has been that Golden Age souls have inherent "dormant" vices that spring to life after natural degradation over time (which also does not fully explain how natural nature itself gets worse if everything was perfect, and how the apples and grapes in the Golden Age become less tasty over time). One day, maybe during the Copper Age (or even before ?) I suddenly become
lusty, and a few days later, get
angry because my
atttached partner has been
greedy and eaten all the chapattis, and so all hell breaks loose thereafter.
I agree with John, that karma, at the outset, looks like a simple understanding of receiving the benefits or punishments from your actions. However, you only reap the benefits when you are UNAWARE of your actions, however we are told to do service and have positive actions and thoughts in order to achieve a high status ... which means you are aware of your actions so as to produce good results, which therefore defeats the very objective from the start. If you are pure enough to know that that you do not even know or aware that you have become pure, then I believe you have reached your goal. But in Raja Yoga, you are told to be number one, to be equal to God, in which case you are continously measuring yourself, and in essence proving something which is unattainable.
I do believe in doing good things for things and others, but not for the sake of what is around me, but for the conscience that is inside me. Whether it is within 1 year or 5000 years, with destruction or no destruction. Have seen many souls "fear" of doing certain things in case it turned out to be bad karma, which again really means they are expecting to reap the benefits before they even start out the very action.
Anyway, have yet to fully understand what is "karma", although someone else previously has said it is just something humans have made up since God does not need it.
