Hello. If you are a seeker of knowledge like me, you might have had the same experience where the information you were gathering kind of got your brain to overload. Well, at least that's how it was for me from the beginning of my awakening. I used countless of hours on YouTube and other sites to gather as much information as I could about the awakening experience, that including quantum physics and just general knowledge about truth. From that time and up until recently I've had trouble piecing it all together.
Anyhow, if you've had a similar experience I would recommend this 1:20 hour long lecture from Billy Carson where he makes it quite simple to understand the big picture of it. Sadly he did not have enough time to go through it all, and he was rushed to finish off when he came to the part about the merkaba. But there are still other sources of information to help with the actual merkaba activation.
