Our hunter-gatherer ancestors were not always cooperative, though. And religion, in turn, bonds people together and permits cooperation among much larger populations than chimpanzee troops can sustain. In addition, language allows people to communicate about abstract concepts such as religion.

On the origins of language, however, Harari is more certain: It evolved as a way for social animals to gossip about other people’s reputations. He correctly points out that it’s not entirely obvious what first spurred the development of our species’s extraordinary intelligence. Harari ponders the considerable energy cost of maintaining such an expensive thinking organ and the concomitant atrophy of our physical strength compared with other primates’. The Cognitive Revolution arose from the evolution of the massive human brain. The author structures this ambitious journey around three momentous events that have irrevocably shaped the destiny of humankind: the Cognitive Revolution, the Agricultural Revolution and the Scientific Revolution. “Sapiens” takes readers on a sweeping tour of the history of our species.

I enjoyed his speech very much, but it is in Tamil language.Harari’s thinking is amplified in his new book, which has quickly become an international bestseller. in actual tale, Shiva is said to dance between the horns of Nandi and Sivam says that is none other than the spot on the forehead between the brows. He controls the breath and thus he controls the existence.Īlso Sivam beautifully explained how the cosmic dance of Shiva, on the Pradosham time period, is to be understood as the spot between the brows, a certain meeting point of the nadis. Sivam says this is why Shiva is termed the 'destroyer'. Just as a dancer who dances in a 30ft long stage, and moves ahead 10 ft but moves back only 5 feet will fall out of the stage at some point, so also, breath or 'Siva' is channeled out only in measures and at that rate, at some point, we all stop the process and hit the end. Yesterday I listened to a discourse by Suki Sivam and he spoke about Shiva.īreath is known as 'Vaasi' (as in 'Vasi yogam' a breathing technique) and Suki Sivam says the intake of breath, as the way it is received by the naadis as in the First In First out principle is thus 'Siva' (the reverse of Vasi) and thus when we breath out, it is 'Siva'. Of course being Tamilian, I have heard of Thirumanthiram.
