Why I Chose to Connect Science, Psychology, Philosophy, Religion and Yoga
One of the questions I am asked quite often is why User Manual for a Human Being brings together subjects that are usually studied independently. Science, psychology, philosophy, religion, and Yoga have evolved through different traditions, use different methods of inquiry, and are often taught as completely separate disciplines. Universities dedicate individual departments to them, researchers spend entire careers specialising in one field, and readers generally approach them through separate books. At first glance, combining all of them into a single work appears unusual. Yet, during the years I spent researching and writing this book, I gradually realised that separating these subjects often prevented us from seeing the larger picture they were collectively trying to describe.
When I first began exploring these disciplines, I had no intention of writing a book. Like many people, I was simply trying to understand life more clearly. Questions about human behaviour naturally led me towards psychology. Curiosity about the human body and the universe encouraged me to read science. Philosophy introduced entirely new ways of thinking about existence, knowledge, and ethics, while religious literature preserved centuries of observations about human life through stories, symbolism, and tradition. Yoga, on the other hand, offered something different altogether. Rather than asking me to simply think about these questions, it encouraged me to observe my own experience directly. At that stage, I still regarded these as separate areas of learning, each offering valuable insights but addressing different aspects of life.
As the years passed, however, I began noticing an interesting pattern. Although these disciplines used different language and followed different methods, they repeatedly returned to many of the same fundamental questions. Science tried to understand the origin of the universe, the evolution of life, and the functioning of the human body. Psychology explored thoughts, emotions, memory, behaviour, and decision-making. Philosophy asked what it means to know something, what consciousness is, and how a meaningful life should be lived. Religion attempted to answer similar questions through stories, traditions, and moral teachings, while Yoga encouraged individuals to explore many of these questions through disciplined observation of the body and mind. The more I studied them, the more I realised that the questions themselves were remarkably similar even when the answers appeared different.
This observation gradually changed the way I approached learning. Instead of asking which discipline was correct, I became more interested in understanding what each discipline could contribute to the conversation. Science possesses extraordinary methods for studying the physical world through observation and experimentation. Psychology helps us understand behaviour, cognition, and emotion through systematic research. Philosophy encourages logical inquiry and challenges assumptions that we often accept without question. Religion preserves values, cultural wisdom, and symbolic teachings that have guided societies for generations. Yoga contributes something equally important by encouraging direct personal experience rather than intellectual discussion alone. Each perspective appeared incomplete when viewed in isolation, yet together they began revealing a much broader understanding of what it means to be human.
One simple example illustrates this clearly. Consider something as ordinary as stress. A doctor may explain how stress affects hormones, the nervous system, and physical health. A psychologist may examine thought patterns, emotional responses, and behavioural habits that contribute to stress. A philosopher may ask whether our expectations about success, identity, or control create unnecessary suffering. Religious traditions may encourage compassion, forgiveness, gratitude, or acceptance as ways of approaching difficult situations. Yoga may offer practical techniques involving breath, posture, relaxation, and meditation to help regulate both body and mind. None of these explanations invalidates the others because each observes the same human experience from a different perspective. If we rely upon only one explanation, our understanding remains limited. When these perspectives are viewed together, they complement one another remarkably well.
This idea became one of the central principles behind User Manual for a Human Being. My intention was never to argue that every discipline ultimately says exactly the same thing because that would not be accurate. There are genuine differences, disagreements, and areas where conclusions remain uncertain. However, I also felt that focusing exclusively upon those differences often prevented us from appreciating how much these disciplines can learn from one another. Knowledge has always progressed when different perspectives were allowed to interact. Scientific discoveries have transformed medicine, psychology has influenced education, philosophy continues shaping ethics, religion has preserved cultural identity, and Yoga has helped millions develop greater self-awareness. Human life itself is not divided into separate compartments, so understanding it rarely comes from studying only one dimension in isolation.
Travelling across India strengthened this understanding even further. During my journeys, I met scientists, doctors, yoga teachers, entrepreneurs, monks, students, labourers, and ordinary families whose educational backgrounds and life experiences differed enormously. Their vocabulary often reflected different traditions, but the concerns they expressed were surprisingly familiar. Everyone wished to understand happiness, suffering, relationships, fear, purpose, health, and peace of mind. The questions remained remarkably consistent regardless of culture, profession, or belief system. This repeatedly reminded me that while our explanations may vary, the human experience itself remains deeply shared.
Another important realisation emerged while organising the chapters of the book. Human beings do not experience life through separate subjects. When someone struggles with anxiety, they are not facing only a psychological issue. Their physical health may influence the situation. Their relationships, beliefs, lifestyle, past experiences, and understanding of themselves all become part of the same experience. Similarly, when someone begins searching for meaning, they often discover that no single discipline provides every answer they are looking for. Science explains many aspects of the external world with remarkable precision, yet philosophy asks different questions about meaning and ethics. Psychology explains behaviour but does not necessarily address every existential question. Yoga encourages direct observation, while religion often preserves symbolic wisdom accumulated over centuries. The complexity of human life naturally invites multiple perspectives rather than a single explanation.
This understanding also shaped the writing style of the book. I deliberately avoided asking readers to accept conclusions simply because they appeared within its pages. Instead, I wanted each chapter to encourage observation, reflection, and independent thinking. Whenever different viewpoints existed, I believed it was more valuable to present them honestly than to force an artificial agreement. My hope was that readers would not simply memorise information but would begin connecting ideas through their own experiences. Genuine understanding develops when knowledge becomes personally meaningful rather than remaining a collection of isolated facts.
Looking back today, I realise that User Manual for a Human Being is not really a book about science, psychology, philosophy, religion, or Yoga individually. It is a book about the human being, viewed through multiple lenses that together provide a more complete picture than any one discipline could offer alone. Every chapter attempts to contribute another piece to that larger understanding, gradually moving from the origins of the universe towards the nature of human consciousness, while encouraging readers to remain curious throughout the journey.
Perhaps this is why I chose to connect these subjects within a single work. Human life is too vast and too complex to be understood completely through only one perspective. Every discipline contributes something meaningful, every tradition preserves valuable observations, and every sincere inquiry has the potential to deepen our understanding. Rather than asking readers to choose one path and reject the others, I wanted to encourage a different approach—one that values curiosity over certainty, observation over assumption, and understanding over blind acceptance. That spirit of exploration became the foundation of the book, and it continues to guide every article I write, every class I teach, and every question that still inspires me to keep learning.
