We take from the source, the unlimited source.
So we should ONLY read the Murlis, and thus forget the rest such as classes held by Dadi's, Senior's classes, Raja Yoga books and courses, Living Values Books, etc ? And even this forum ?
Nowadays, you can get a bottle of mineral water from the Alps or Andes halfway round the world though it is bottled locally. Well, that is what it says on label. Well, you drink that water on The Knowledge that it comes from the source (from a physical spot on the earth). Do you go to check the source of the water ? No, you go and ask the bottlers who are authorised and have patents and legal and scientific and government papers what nots. Basically you have someone to ask.
So I'll ask DJ where she got this class from, and ultimately it would be from The Supreme Soul, through the Murlis. The Knowledge that all these BK information is therefore all coming from the Murlis, or the closest interpretation that BKs can edit and write about them in maybe a more simpler and digestible manner, at least to start with. Now, we've progressed and begun to understand more, our thirst is greater. Go to the source..visit Madhuban.... but where are the original Murlis ?
One has to remember that any classes that Dadis give, even though there is much to take from and I have also learnt much from them myself, is ultimately only a reflection of their own experiences with the Supreme Soul. It may not be the same for you. A class given by Dadi pre 1976 maybe different to that after 1976. Well, it depends if the Murlis during that period are the same as the Murlis of today. (Murlis in this case are the daily morning BK Sakar Murlis)
