It is quite obvious to almost everyone that there is an experience-based mental reality whose content passes as information in our nervous system and unites our external bodily senses with the mental ones. But fewer people dare to take on the balancing act of meeting the mental reality on the individual terms it presupposes in the form of seclusion and stillness with which we in our everyday lives distract our self-observation by clinging to and identifying with what our external senses provide us with. They are what they are in themselves and convey their impressions to us through their functions. But when their properties are not separated from our mental reality and united in a naive and undeveloped way, body and mind become the same thing. Our mental reality loses its inter-human significance and we are plunged into a kind of medieval psychic darkness. I have realised that these opposites are united in an intermediate state and it is through the transformation we undergo in this state that we encounter it. We directly experience the interaction we have between our external senses and the content of our mental reality. How we mix them up with each other, and attach ourselves to substitute objects for the content of our psychic reality, leading to a continuous cycle of confusion and severe mental torment. In traditional India, this happens when Indriya becomes our inner Āyatana. Which means that our entire world as we perceive it, when filtered through our external senses and united with the properties and content of our mental reality, becomes one and the same. We become attached to chains of dependence on our external senses. By what they excite within us without perceiving where they originally arose. We cannot perceive that we have a mental quality that is crucial to understanding what insight is, which gives us the ability to observe the content of our mental states without being distracted by our external senses. Indriya is this ability. When everything becomes one and the same, Indriya becomes Āyatana. A defiled version of Indriya and mental ignorance. We can say that we possess a mental function whose property is to work in conjunction with our psychic processes, with all the input of our inner and outer senses, and to serve as a threshold to mental reality. This means that we have gained a sense of a liberated consciousness. No attachment arises in the contact between mind and object. And from this perspective, it acts as our primary accountant for the content of what arises in our psychic reality. We relate to it as wisdom. It is where our center of experience have mental home.
