The core of what is defined as Perennial Philosophy is established by ancient traditions of metaphysical thought, which, though arising from the most various historical contexts from East to West, outstandingly share some fundamental truths such as the mutual interrelation of all things. However, even more astonishingly is how the insights of contemporary physics currently back up these various truths which spread among different cultures. This paper aims at underscoring how undeniably compelling. Yet, uncanny this bond is, primarily on the plane of knowledge, a broader knowledge substantiated by science and philosophy - the two speak here an unknown language, yet with the same voice: the incommunicability of their truths overlapping with the incommunicability of their actual experiences. Grappling with the dazzling disclosures of these "mirrors of knowledge" is as fascinating as unavoidable. This study takes into account some of them by uncovering how crucial they are both for the present and the (albeit acknowledged by the past wisdom) future understanding of the reality we are entangled with.
