Seventy-five thousand years back, the ‘Cognitive Revolution’ happened, and the human ‘brain’ was ready to create the human ‘Mind.’ The primary animal thoughts of survival tactics evolved into religious/sociocultural ideas transforming the herds of hunter-gatherer Homo sapiens into religious, social, and cultural groups. The three existential questions “Where from I(We) came?”, “Where I(We) will go?” and “Who am I? or Who we are?” gradually became the epicenter of human enterprise. Evolutionary forces created the intelligent human mind with its extraordinary ecosystem of thought processes developing a controlling, communicating, balancing, and modulating ‘Spiritual Thought Processes’ and thoughts of ‘Spirituality.’ This is an incredible story of complex, ambiguous, mysterious, but incredibly attractive evolved human thought of spirituality and its evolutionary neurobiology.
