Search Inside Yourself

Chade-Meng Tan, an early engineer at Google, presents a mindfulness-based emotional intelligence curriculum he developed at the company, arguing that contemplative practices can be made accessible, practical, and beneficial for ordinary people in modern workplaces. The book grew out of a course called Search Inside Yourself (SIY), taught at Google since 2007, which combines ancient meditative wisdom with contemporary neuroscience and emotional intelligence research. Tan's broader aim is to contribute to world peace by spreading inner peace and compassion through these practices.

Tan opens by introducing Matthieu Ricard, a French molecular geneticist who became a Tibetan Buddhist monk and whose brain, when scanned by scientists, registered the highest happiness levels ever measured. Ricard also demonstrated the ability to suppress his startle reflex during meditation and to detect fleeting facial expressions with exceptional accuracy. Tan uses Ricard's example to argue that such mental capabilities are accessible to anyone willing to train. He then describes how a group of Google engineers created SIY with collaborators including a Zen master, a CEO, a Stanford scientist, and Daniel Goleman, author of the influential book Emotional Intelligence. The course operates in three steps: training attention to develop a calm and clear mind, using that attention to observe one's cognitive and emotional processes with high clarity, and cultivating mental habits such as instinctive goodwill toward others.

Tan defines emotional intelligence using the framework of psychologists Peter Salovey and John D. Mayer as the ability to monitor one's own and others' emotions and use that information to guide thinking and action. He presents Goleman's five domains: self-awareness, self-regulation, motivation, empathy, and social skills, and argues emotional intelligence is a learned capability rather than an innate trait. He cites research showing emotional competencies distinguish star performers more reliably than intellectual abilities, and a U.S. Navy study showing the most effective commanders are warmer and more sociable. Tan introduces neuroplasticity, the principle that the brain's structure and function change in response to experience, as the scientific basis for training emotional intelligence in adults. He establishes mindfulness as the foundational method, explaining that stable, non-judging attention enables both self-awareness and the capacity to pause before reacting.

The book provides detailed instructions for mindfulness meditation, defining it as a family of mental training practices designed to familiarize the practitioner with specific mental processes. Tan explains that mindfulness trains two faculties: attention and meta-attention, the ability to know when attention has wandered. Drawing on meditation teacher Alan Wallace, he presents the claim that happiness is the mind's default state, to which it returns once it becomes calm and clear. He walks through the meditation process step by step, from setting an intention to following the breath, handling distraction without self-criticism, and adopting an attitude of self-directed kindness he calls "grandmother mind." He surveys scientific evidence including a study by neuroscientist Richard Davidson and mindfulness researcher Jon Kabat-Zinn showing that eight weeks of mindfulness training in a corporate setting reduced anxiety, increased positive brain activity, and boosted immune response.

Tan extends mindfulness beyond formal sitting into everyday life through walking meditation, mindful listening, and mindful conversation. Mindful conversation consists of three components: listening with full attention, looping (repeating back what one heard until the speaker confirms understanding), and dipping (checking in with one's own feelings during the exchange). He reports that just six minutes of mutual mindful attention between strangers often suffices to create a friendship.

The book devotes significant attention to self-awareness, which Tan identifies as the key domain enabling all other emotional intelligence skills. He introduces the body scan, a systematic practice of bringing non-judging attention to different body parts, adapted from Kabat-Zinn's Mindfulness-Based Stress Reduction (MBSR) program, and journaling as a tool for self-discovery. He cites a study in which laid-off professionals who wrote about their feelings for five days found new jobs at dramatically higher rates than a control group (68.4 percent versus 27.3 percent). The chapter culminates in a critical insight: With practice, the experience of emotion shifts from existential ("I am angry") to physiological ("I experience anger in my body"), opening the possibility of mastery over emotions.

Tan frames self-regulation as moving from compulsion to choice, clarifying that the goal is not to suppress emotions but to work skillfully with them. He introduces the Siberian North Railroad (SBNRR), a five-step practice for handling emotional triggers: stop, breathe, notice (experience the emotion physiologically), reflect (examine the emotion's origins and consider the other person's perspective), and respond (imagine the kindest possible response). He concludes the chapter by framing self-regulation as befriending emotions, citing Tibetan Buddhist teacher Mingyur Rinpoche's account of overcoming a panic disorder at age 13 by making friends with his panic rather than treating it as a boss or an enemy.

The chapter on self-motivation introduces three practices: alignment (connecting work with one's deepest values), envisioning (imagining oneself achieving a desired future), and resilience. Tan draws on Zappos CEO Tony Hsieh's framework of three types of happiness: pleasure (highly unsustainable), passion or flow (more sustainable), and higher purpose (highly sustainable), arguing people should devote most energy to higher purpose. He tells the story of Roz Savage, a London management consultant who wrote two versions of her own obituary, discovered that her current trajectory drained her while her ideal life energized her, and went on to become the first woman to row solo across the Atlantic and later the Pacific Ocean. Drawing on psychologist Martin Seligman's concept of explanatory style, Tan distinguishes optimists, who see setbacks as temporary and isolated, from pessimists, who see them as permanent and pervasive, and outlines steps for learning optimism through mindful attention to one's habitual thought patterns.

Turning to empathy and social skills, Tan describes mirror neurons as a possible neural basis for empathy and explains that empathy relies on the same brain structures as self-awareness, meaning practices that strengthen one simultaneously strengthen the other. He introduces the Just Like Me and Loving Kindness practice, in which one reminds oneself of similarities with another person and then generates wishes for their well-being. He argues compassion is the happiest mental state ever measured, citing brain scans of Ricard and other meditators, and connects compassion to effective leadership through management researcher Jim Collins's concept of "Level 5" leaders in Good to Great: those possessing both ambition for the greater good and personal humility. Tan introduces the Multiplying Goodness Meditation, in which one breathes in goodness, visualizes the heart multiplying it tenfold, and breathes it out to the world. He also covers neuroscientist David Rock's SCARF model, which identifies five domains the brain treats as primary rewards or threats: Status, Certainty, Autonomy, Relatedness, and Fairness. He discusses conducting difficult conversations using the Harvard Negotiation Project's framework, which identifies three layers in every conversation: content, feelings, and identity.

The final chapter tells the origin story of SIY as a vehicle for Tan's dream of world peace. He outlines three steps: cultivating constant kindness in himself, making meditation scientific, and aligning meditation with real life. His epiphany came from reading Goleman's Emotional Intelligence, which revealed that emotional intelligence was the perfect vehicle because everyone already values it, its greatest side effect is inner happiness and compassion, and the best way to develop it is through mindfulness. In the epilogue, Tan reflects that striving to save the world is unsustainable; instead, focusing on inner peace and compassion allows compassionate action to arise naturally. He closes with Vietnamese Zen Buddhist teacher Thich Nhat Hanh's teaching that after stilling the mind, "you don't take action; action takes you" (241).
