Time is the fourth dimension, in addition to the length, width and height of the usual spatial cognition of our world, though most may not realise its ubiety. It is what takes our square existence beyond the humdrum two-dimensional flatness, beyond even the stereoscopy of the cube to the refracting multifacetedness of the hyper-cube, the tesseract. Understanding the tesseract, then, is the key to understanding the story of us and deciding the way forward.Nowadays, when information is abundant but discernment is not, truth very often gets obscured. Only a detailed chronicling of time – our times – reveals the intricate contours of the tesseract, the geometry of truth, going beyond the 3D of what has been all-too-easily accepted as reality down the ages, or even the only reality. Time provides the crucial context, tracks and marks every change, and therefore determines the diverse perceptions of truth too.Humankind has been on a quest for truth even before the concept of time dawned on us. Beyond what was, what is and even what will be, though, is the fourth axis of ‘what could’. It has always been there but not perceived until minds were awakened to its prescience. Transcending the three axes to the reflective fourth one, the tesseract, has become an imperative in our times of clashing truths and blinding contradictions that defy reason and confound the mind.A tesseract is complex but not complicated. As a metaphor for our space-time continuum, it is lucid and yet profound, liberating and illuminating, and yes, utterly mind-bending and mind-blowing in its vividness. When the curtain rises on The Tesseract: The Geometry of Truth at the National Centre for the Performing Arts (NCPA) in Mumbai today, take a journey into the story of our times and understand the clarion call to Let Truth Prevail.
