The Germans interestingly enough, have a word, Grenzbegrifflich, which describes that which is very real but is beyond analysis and description.
When l’ m talking about your intuitive sense that reality at its deepest flows from a being/energy that is grenzbegriff. 

Intuition is the ability to understand something immediately, without the need for conscious reasoning.

Instinct is our inclination toward a particular understanding (as opposed to a learned response), and it is also known as ‘gut feeling’, or ‘a hunch’, a sensation that appears quickly in consciousness without us being fully aware of the underlying reasons for its occurrence.
Intuition is a process that gives us the ability to know something directly without analytic reasoning, bridging the gap between the conscious and Xconscious parts of our mind..

We need both instinct and reason to make the best possible decisions for ourselves, our businesses, and our families. Unfortunately, many of us—even when we experience success using this lesser acknowledged part of us-are uncomfortable with the idea of using our instincts as a guidance tool.

From a spiritual perspective intuition can also be interpreted as one of the ways that Love energy, God or our Xconscious Higher Power communicates non-verbally, in the same category as dreams, emotions, artistic creativity etc.

“Our inner personal trainer encourages us through our dreams, emotions and rich, unique, individual awareness.

Don’t complain you don’t have daily guidance –it shines within each open heart.”

One heartening historical tradition which is embedded in every culture is that of silent listening or ‘inner work’. This is one way that the experience of the ‘other’ can be known. It can be called meditation, yoga, contemplation or ‘sitting quietly listening to nature’, and through these practices the universal intention to love can be heard. This practice opens up space within us, and we can discover who we truly are, by tapping into the energy within. We are used to the noise of the world, but the most important personal messages arrive with no noise at all.

These ‘inner dynamics’ refer to anything that goes on inside you, any energy system that lives and acts from within you. It may be an emotional event, such as a surge of anger. It may be an inner conflict, an inner personality acting within you, a feeling, an attitude, a mood. It is from these inner dynamics that we can learn to understand what is going on inside.

St. Francis of Assisi gave us this inspiring poem; “There are beautiful wild forces within us. Let them turn the mills inside and fill sacks that feed even heaven.”

Attending to inner dynamics using intuition is inner work.

“Intuition doesn’t seek “the truth” or even sense. Intuition is completely open to non-sense. It dives down into the depths of the unconscious where reason and instinct collide in unexpected ways, and it latches onto hidden connections and contradictions.
Then it brings this information- via an unusual sign, a rare sensation, an unexpected feeling, or a seemingly irrelevant fact-to the surface of consciousness to feed the rational mind and enable logic to work with paradox.
Intuition empowers us to operate in the zone of ambiguity and change, the exact place where imagination and genius occur.

Intuitive Intelligence helps us survive in new and changing environments by incorporating intuition and instinct into our thought process and our business endeavors.
The purpose of instinct is survival. Its ultimate mission is to ensure the sustainability of our species. It understands how to collaborate with and adapt to our ecosystems. This is its inherent wisdom. This is why Intuitive Intelligence is so needed today.

We access our Intuitive Intelligence via the Intuitive Compass. The Intuitive Compass helps make sense of chaos and leverage its power. It is an actionable model that applies Intuitive Intelligence in practical situations.
It is based on fundamental dynamics of human performance: the tension between linear efficiency and random play, and the synergy between reason and instinct.”
