It's understood in metaphysical circles that the function of intuition is strongly related to heart energy, or love. This seems to be somewhat different from other forms of psychic manifestations that are mostly attributed to the third eye. This means that we are relating to our environment and accepting of our place in the world. Intuition appears to be a sense similar to instinct, and quite possibly there is a relationship between the two. Heightened instincts are evidenced by an intense awareness of the environment, spatial relationships and motion.
Intuition also appears to be a heightened awareness of the environment, but on a different level.
When reduced to analytical concepts, intuition can be compared to lightening fast calculations which can determine statistical probabilities and deduce a likely outcome. As I said, this was reducing the activity to analytical concepts. But, as we've been told, the heart has its own wisdom. I've seen that this idea is often accepted only as a figure of speech, and not as literal truth. This is what appears to be the case though.
