Spirituality and its Evolution

The early Homo-Sapiens, the ancestors of modern man had resorted to ceremonial burials around 30-40 thousand years ago, for the welfare of the souls in the afterlife hinting that they believed in some form of elementary spirituality. Such belief of the Homo sapiens had, later, led to growing beliefs of 'animism' and shamanism. The turning point in the lifestyle of the Homo-sapiens came since around 11700 years ago with the coming of the warmer climate of the Holocene period

facilitating the growth of cereals, crops, and the rearing of animals while living a life of sedentary agricultural farmers. Security of food and shelter has caused a cognitive revolution in humans to innovate faiths and religions. Yoga and asceticism had been innovated in the Indus Valley Civilization igniting the light of spirituality for the entire world. Neuroscientists have of late, undertaken a number of researches on the meditational impact on the brain; based on the findings, neuroscientists suggest that feeling of religiosity, godliness or spirituality is generated due to the impact of meditational practices and that such feelings can be regenerated artificially by manipulating specific region of the brain. The book thus goes to discuss, briefly, all the related issues on spirituality.
