"Mind" in reference to something absolute has gotten a lot of use especially in zen. My sense of the use of the term "Big Mind" is that its at least a little farther away from the sense (as i understand it from looking at some of the vids and some reading) in which some zen ancestors used the term "Mind" and it might be helpful to look at some of the earlier uses of "Mind" as background.
This for instance from the intro to "The Zen Teachings of Huang Po" translated by John Blofeld:
The text indicates that Huang Po was not entirely satisfied with his choice of the word “Mind” to symbolize the inexpressible Reality beyond the reach of conceptual thought, for he more than once explains that the One Mind is not really MIND at all. But he had to use some term or other, and “Mind” had not often been used by his predecessors. As Mind conveys intangibility, it no doubt seemed to him a good choice, especially as the use of this term helps to make it clear that the part of a man usually regarded as an individual entity inhabiting his body is, in fact, not his property at all, but common to him and to everybody and everything else. (It must be remembered that, in Chinese, “hsin” means not only “mind,” but “heart” and, in some senses at least, “spirit” or “soul” – in short, the so-called REAL man, the inhabitant of the body-house.) If we prefer to substitute the word “Absolute,” which Huang Po occasionally uses himself, we must take care not to read into the text any preconceived notions as to the nature of the Absolute. And, of course, “the One Mind” is no less misleading, unless we abandon all preconceived ideas, as Huang Po intended.
I dont think there is anything really new about "Big Mind" except the packaging and marketing and imo it never helps to further objectify ideas like this.
