These are questions over which there is much confusion. Firstly, it has been proved by human biologists that the physical heart is full of (striated) brain cells, which are the same kinds of cells as most of the brain is made of. Also, that the human gut area, near the solar plexus, has three thin layers of the same cells. Because of this, the advice to “think with your heart” or “think with your gut” regarding your major choices does make sense. That’s because the thoughts (i.e., the things that cause electric currents conveying certain information) coming from the brain cells in either of those parts of the body will be much less muddied by your conditioning.

The word “heart” is ambiguous, though, because the word “feeling” is ambiguous. If somebody says “Follow your heart”, that’s basically very good advice (subject to some taking account of practical considerations) if what they mean is “Follow your intuition”. Our intuition is sixth-dimensional, our intellect/thoughts are fifth-dimensional, our emotions are fourth-dimensional, and our bodies three-dimensional. If you really get in touch with your intuition, that will “feel right” emotionally and hence bring you joy, it will “make sense” intellectually, and even “make sense” in a different way physically, by causing your body to be pleasantly relaxed.

Regarding “hive mind”, most of your thoughts or feelings aren’t original, but simply recycled "clones" of thoughts or feelings. They could only be original if you created an original idea out of the nothingness. Ideas come from the (lower) sixth dimension, so you need to create it there. In the sixth dimension, intuitions or ideas are a type of “feeling”, but one that is quite different from emotional feeling. At first you won’t be able to put the idea into words, until you manage to bring it down into the fifth dimension. At almost the same time, you’ll then give it birth in the fourth dimension also, at which point you’ll have emotion/feeling about it.

If you’re interested, I know that some of Sri Aurobindo’s writings cover these sorts of subjects in great detail. You’ll find that scholars of comparative religion generally regard Aurobindo’s writings as very much the greatest and most wise and the most detailed works there are on what spirituality really involves. (Aurobindo is also universally regarded in India today as one of the greatest gurus ever.)
