Every individual on this planet has access to the fundamental basis of all knowledge, all understanding, all inventions, ideas, thoughts, and concepts. This basis is consciousness.
Every individual has the potential capacity to understand reality, the basis of reality, thought, consciousness itself, and many other phenomena, without the aid of invention. Invention itself has it's foundation in consciousness; our consciousnesses ability to imagine a method or thing and to shape reality, indeed existence itself, to our will.
Reality; knowledge, perception and thought, is dependent on consciousness; to understand consciousness is to understand reality.
