There is a story according to which C.G. Jung, the well-known psychiatrist, met while their journey to Mexico with an Indian named Ochwiä Biano (mountain lake), this one comment:
The whites always want something, are uneasy and restless. We do not know what they want. We do not understand them. We think they’re crazy.
When Jung asked him why he believed that all white men were crazy, the Indian replied:
They say they think with their heads.
Jung, surprised, said: “of course, don’t you do so way?”, and the Indian, pointing to his heart, said: “We think here.”
Actually now a days there are a revival of the role played for the body in decision making, strange as it can seem for our intellectualized society; there are IQ, intelligence quotient, but also EQ, emotional quotient, and emotions born both from body and mind, and even SQ, spiritual intelligence quotient. The body reacts to the environment independently of the intellect, and with training we can feel their instinctive messages. If Jung was true with their theory of collective unconscious, our body, thought the individual unconscious, is able to connect with the collective one and get information beyond the scope of our intellect.
Maybe the ancient tribes was true, and the excessive use of intellect in the developed societies is the source of most of our troubles, maybe is time to recover our body intelligence, our connection with the Nature and the whole.
