"Sense". Taste, sight, touch, smell, hearing are the five commonly known senses. Since ancient times the ancient shamans of Asia, Africa, America, Oceania and also in prehistoric cultures of Europe have the faculty to heal, to communicate with the spirits and ancestors, and to present visionary and divinatory abilities basing their work on precognition or clairvoyance.
Phrases like be guided by your instinct, follow your heart only mention that sense. Intangible, invisible, asleep and untrained sense, but is everything that surrounds us visible? Do we all perceive the world in the same way or each body is a different filter?
