Well, maybe not a spook, just someone with an agenda to promote. My own agenda that I promote is accurate and right knowledge of yoga philosophy. As part of my agenda, I attempt to expose others who provide inaccurate or false knowledge, as they only serve to create confusion and division.
So, Mr. Seeker, can you tell us what are subtle thoughts, and how are they different from thoughts that are not subtle? And what does this have to do with the past, which was supposed to be the topic of this thread? Please provide references for your interpretation of “vichara” as “subtle thoughts”, as this is quite different from every other translation that I am aware of.
