In the vast intellectual landscape of India, where the spiritual quest for truth has long walked hand-in-hand with rigorous reasoning, the scientist’s journey is not merely external, it is deeply internal. Yukti (युक्ति – reasoning) and Yatharth (यथार्थ – reality) are two pillars that have guided Indian philosophy for centuries. Today, they also frame the inner paradox faced by scientists, how to reconcile the logic of the laboratory with the silence of the soul.
The Dual Identity of the Indian Scientist
An Indian scientist lives in two worlds. On one side lies a world driven by empirical validation, peer-reviewed publications, and the objective rigour of modern science. On the other, there lies the substratum of India’s philosophical tradition, where consciousness is not merely a by-product of the brain but the very fabric of the universe. A question arises – Are we merely observers of an impersonal cosmos, or participatory agents of a deeper, conscious order?
Ancient Indian texts like the Upanishads have long posed this question. “आत्मा वा इदमेक एवाग्र आसीत्” (in the beginning, there was only the self) (Brihadaranyaka Upanishad). The scientific mind, trained to separate observer and observed, often finds itself at odds with such unity-based metaphysics, but it is precisely this conflict that characterises the scientist’s inner struggle.
YuktI: The Imperative of Rationality
Yukti, or logical reasoning, is not a Western import. Indian thinkers like Acharya Kanada (founder of the Vaisheshika school) and Nagarjuna (of the Madhyamaka school) employed razor-sharp logic to arrive at metaphysical conclusions. Mimamsa and Nyaya philosophies elevated rational debate to a fine art. In this tradition, the pursuit of knowledge (Vidya) was grounded in methodical inquiry, not mere belief.
Today’s scientists, whether physicists studying quantum entanglement, or biologists decoding cellular mechanisms, are heirs to this long tradition of yukti. It is through this lens that they interpret data, formulate hypotheses, and conduct experiments. However, the deeper questions, What is consciousness?, Where does meaning arise?, What is the self ?, often escape the grip of conventional rationality.
Yatharth: Truth Beyond Equations
Yatharth is not simply the ‘truth’ one sees in a lab result. It refers to Tatvamasi “Thou art that”. It is the realisation that the seeker and the sought are not separate. Here lies the scientist’s deeper crisis, scientific models can describe reality, but can they become reality? A physicist can measure time dilation, but can he grasp what time truly is without being rooted in the present?
Modern science has evolved tools to peer into the microcosm and macrocosm, from gene editing to gravitational waves. Yet the inner cosmos remains elusive. In Indian tradition, this gap is bridged through sadhana (साधना), not just meditation or yoga, but a disciplined pursuit of self-knowledge. The scientist who turns inward begins to see the limits of the mind as clearly as the limits of an instrument.
The Clash and Convergence
This tension between Yukti and Yatharth becomes most visible in moments of personal, or scientific crisis. When a theory fails, when a model collapses under data, or when the pressure of publications undermines personal peace, the scientist often begins to question, What is this pursuit for?
Many Indian scientists, from Jagadish Chandra Bose to C V Raman, were not strangers to this internal duality. Bose, in particular, saw no contradiction between his study of plant electrophysiology and his belief in the unity of all life. In his words, “The same stream of life that runs through my veins runs through the roots of the plant”. Raman once remarked, “Ask the right questions and nature will open the doors to her secrets.”
Such statements show that for many Indian scientists, scientific truth and spiritual truth were not mutually exclusive. Rather, they were two eyes of the same vision.
Science, Self and Indian Civilisation
The National Education Policy (NEP 2020) emphasises ‘holistic, multidisciplinary education’, a much-needed call in a world where specialisation often blinds us to the larger picture. For Indian science to truly thrive, it must embrace its cultural inheritance. This is not to dilute scientific rigour with dogma but to enrich it with introspection.
As Swami Vivekananda observed, “Science and religion will meet and shake hands”, but for that to happen, both sides must see themselves not as opponents, but as collaborators in the grand quest for yathaarth.
In this light, the scientist’s struggle with the self is not a weakness, it is the very ground of innovation. When Einstein was stuck with the equations of general relativity, he turned to visual imagination, a technique closer to meditative visualisation than strict calculation. Schrödinger, who admired Indian philosophy, said, “The multiplicity is only apparent; this is the doctrine of the Upanishads”.
Towards an Integrated Future
What does an integrated Indian scientist look like?
They are grounded in empirical method, but not enslaved by it. They are open to silence, uncertainty, and intuition, not as alternatives to logic, but as complements. They read Nature and the Gita with equal curiosity. They strive for अनुभव (direct experience), not just अनुमान (estimate). They accept the paradox, that to understand the cosmos, one must also understand the consciousness that observes it.
Ultimately, the struggle of the scientist is not to conquer nature, but to resonate with it. The telescope and the microscope are extensions of the eyes, but the heart and the mind are instruments of another kind. Yukti helps sharpen these instruments, Yatharth gives them direction.
In India’s cultural ethos, the scientist is not separate from the seeker. The lab and the ashram are both sites of discovery. The microscope and the mantra are both vehicles of insight. This is not mysticism, it is realism of the highest order. As the Chandogya Upanishad reminds us:
“यो वेद निहितं गुहायां परमे व्योमन्।
सोऽश्नुते सर्वान् कामान् सह ब्रह्मणा विपश्चिता॥”
(He who knows that which is hidden in the cave of the heart, in the supreme sky, attains all desires along with the all-knowing Brahman.)
The scientist’s ultimate task, then, is not just to decode equations, but to awaken insight, not only to observe reality, but to become it. In this union of Yukti and Yatharth lies the next frontier of science in India.
