The article is devoted to the analysis of the knowledge phenomenon as a metaphysical basis for the being order. It is the semantic content of this word that retains the meaning of “the light of truth”, “reason”, “word”. This allows a human to see the world around him, that is, makes the world “manifested, clear, understandable”. We are talking about knowledge that reflects a purely spiritual nature, which means that this knowledge is directed to the very essence of the human soul. This is, in its essence, valuable knowledge that “heals”, that is, unites, makes all aspects of human nature (spiritual, physical) one whole. Therefore, this knowledge requires a special perception from a person, makes us feel, go deeper into what we know. As an “ether”, that is, an information environment that is able to fill, inspire a person, transform, connect, reproduce his connections with reality, spiritual knowledge leads to the correspondence of the individual to the ontological laws of joint existence. In other words, these are the principles that underlie the integrity of human existence – its development, the formation of the space of co-existence. That is, we are talking about the metaphysical foundations of the order of the universe. In this perspective, we are talking about the fact that the basis of human existence, its correspondence and correlation, is the need for spiritual knowledge. It is the latter that are that transcendental light, which is endowed with transformative potency. Knowing what corresponds to the nature of a person’s sensibility, the needs of his soul. So, the need to discover this knowledge for oneself is cognition, and is the potential force that moves a person in her life choices, builds the meaning and perspective of her life. If we understand human and the world around him as a coexistence, then we are talking about the relationship between the inner state of the individual (his existential attitude) and the world around him, which is a living, dynamic environment. Light is an ontological order et life condition. In its metaphysical status, light is the basis of being itself, and, therefore, that which fills us with life force, which is incompatible with any manifestation of darkness, ignorance, evil. That is why the ability to see the surrounding reality without distortion, that is, objectively, holistically, is revealed only to the person who is the bearer of this light.
