Abstract
“There are things known and there are things unknown, and in between are the doors of perception,” said Aldous Huxley[1]. The world we see and live in depends on how we perceive it. In simple terms, perception is the way we use our senses to understand the world around us.
The ancient wisdom of Vedanta looks deeper into this process through the idea of Pratyaksha Pramana — gaining knowledge through direct perception. While modern science studies how the brain and senses help us know things, Vedanta Paribhasha by Dharmaraja Adhvarendra explains the inner changes (vikaras) that take place in the mind during perception.
This paper aims to connect Cognition and Pratyaksha Pramana, showing how awareness of this process can help us understand both the world and ourselves more deeply. The jnana-janma-krama or the process of the rise of knowledge in Vedanta runs parallel to the modern cognitive process — stimulus, perception, conception, and knowledge — but it also goes beyond it by including the role of consciousness (chit). In today’s world, where we often speak of “mindful living,” this study shows that true mindfulness begins with understanding how the mind works and perceives.

Introduction
Perception plays a central role in our lives. Most of what we know about the world comes from our perception. Modern cognitive science studies perception by looking at sensory input, brain processing, and how the mind forms images of objects.
Advaita Vedanta also explains perception through the concept of Pratyakṣa Pramana, which means direct knowledge. However, its inquiry goes beyond just the physical or mental processes. It asks deeper questions: It asks a deeper question: What is the principle that makes awareness possible?
In the Vedanta Paribhasha, Dharmaraja Adhvarendra offers a systematic explanation of perception. According to Advaita, the ultimate reality is Brahman, pure consciousness. All experiences shine because of this consciousness. The Upanishads state: “तस्य भासा सर्वमिदं विभाति”[2] which translates to “By Its light all this shines.”
The Process of Perception
Perception starts when the sense organs connect with objects, known as indriya-sannikarṣa. This connection brings a change in the antahkarana, or inner mind. The mind takes on the shape of the object, which is called vṛtti.
When we say the mind “goes” to the object, it does not physically move. Instead, it changes in a way that reflects the object.
Two important things happen here:
1. The vṛtti takes the shape of the object.
2. That vṛtti is illuminated by consciousness.
Three Conditions of Consciousness
Advaita tells about consciousness being conditioned in three ways.[3]
1. Vishaya–Chaitanya — Consciousness conditioned by the object. (तत्र घटाद्यवच्छिन्नं चैतन्यं विषयचैतन्यम्)
2. Pramana–Chaitanya — Consciousness reflected in the mental change. (अन्तःकरणवृत्त्यवच्छिन्नं चैतन्यं प्रमाणचैतन्यम्)
3. Pramatr–Chaitanya — Consciousness conditioned by the knower. (अन्तःकरणावच्छिन्नं चैतन्यं प्रमातृचैतन्यम्)
In reality, consciousness is one and indivisible. These differences arise only due to limiting conditions. When the vṛtti is illuminated, knowledge occurs.
Internal Perception
Vedanta acknowledges internal perception as well. When someone says, “I am happy,” that happiness is directly known. It is not inferred; the happiness-vṛtti is illuminated by consciousness.
Since the mind itself is known, it cannot be the final knower. The principle states: “दृगेव न तु दृश्यते” meaning “The seer is never the seen.”
The mind can be seen; therefore, it cannot be the ultimate perceiver.
Comparative Perspective
Modern cognitive science breaks down perception step by step. Objects in the environment act as stimuli. When we focus on them, our senses activate. In vision, an image forms on the retina, which converts into electrical signals processed by the brain. The brain then recognizes the object, and we become aware of it. This explains how perception occurs at physical and neural levels.
The Advaita model is similar until the point where the mind forms a vṛtti corresponding to the object. Both models acknowledge a representational stage.
But a deeper question arises: Is forming a mental representation enough for awareness? Does processing alone lead to experience?
This is known in modern philosophy as the “hard problem of consciousness,” discussed by David Chalmers. It highlights the challenge of explaining how physical processes create subjective experience.[4] Advaita offers a different perspective. It states that everything besides consciousness is inert, including the mind. The vṛtti can clarify our understanding of the object, but it cannot reveal itself. It becomes known only in the light of consciousness.
Shankaracharya beautifully summarizes this: “यस्यैव स्फुरणं सदात्मकमसत्कल्पार्थकं भासते…” which means, inert things only shine in the light of consciousness.
Thus, science explains how perception works, while Advaita explains the illumination behind it. Science focuses on structure, and Vedanta focuses on awareness.
Perception does not create knowledge; it reveals what is already self-luminous.
Philosophical Implication
When we clearly understand that consciousness differs from the mind and its fluctuations, our sense of self changes. We stop fully identifying with the changing body and mind and start recognizing ourselves as the witness awareness. This insight has profound implications in Advaita. Much of human suffering comes from identifying with temporary mental states. When we see ourselves as the awareness that allows all experiences to arise, we gain clarity and freedom.
Conclusion
The analysis of Pratyakṣa in Vedanta not only explains the mechanism of perception but also reveals the deeper reality underlying every experience. While the vṛtti is formed through the senses and the mind, it becomes knowledge only when illumined by Chaitanya.
When compared with modern cognitive explanations, Vedanta does not reject scientific accounts of perception; rather, it extends the inquiry to the fundamental principle that makes all experience possible. Thus, drawing from the wisdom of the Upanishads, we arrive at the recognition that our true nature is that reality which is beyond all dualities – त्वमक्षरं सदसत्तत्परं यत् [5].
