Majority lacks intelligence, we never teach our kids how to think, there are no schools in the world who would teach thinking. Again we teach boundaries. A brain surgeon has his boundary, a civil engineer has his own boundaries. It seems the society allows us to dive in the swimming pools but not in the ocean, because the Ocean is boundryless. Again knowledge is limited and so is ego but intelligence has no limitations.
Intelligence is a quality of awareness but still vague.
If you look deeply nothing is new on this planet. Osho, Krishnimurti, Yogananda, Muktananda, Vivekananda repeated what the Sikh masters had to say 500 years ago. Sikh masters repeated what Jesus, Buddha and Mahavira had already said before. They in turn got their knowledge from the Vedas. From Vedas one can go back to Atlantis and who knows what was before Atlantis.
