Mindfulness: The Ancient Practice That’s Taking Over Modern Life — But Scientists Still Can’t Agree What It Is

Over the past two decades, mindfulness has exploded from a niche spiritual practice into a global phenomenon taught everywhere from corporate boardrooms to military training grounds. But beneath the surface of this wellness craze lies a surprising truth: scientists, clinicians, and educators still can’t agree on what mindfulness actually is—or how to measure it.

The Mindfulness Explosion

Walk into any bookstore and you’ll find shelves dedicated to mindfulness. Open your phone and dozens of apps promise to make you calmer, happier, and more focused through meditation. Google teaches it to employees to boost creativity and avoid burnout. Hospitals use it to help patients manage pain and mental health conditions. Schools incorporate it into curricula to help students focus.

On social media, mindfulness is often reduced to a single image: someone sitting peacefully, breathing deeply, fully present in the moment. But according to Ronald S. Green, a professor of religious studies who has spent years examining how mindfulness is defined across different traditions, this simplified view misses something crucial.

A Practice With Ancient Roots

Mindfulness isn’t new. Its origins trace back thousands of years to Buddhist, Hindu, Jain, Sikh, and other Asian contemplative traditions. The Buddhist “Satipatthana Sutta” emphasizes moment-to-moment observation of body and mind. Hindu “dhyāna” cultivates steady focus on breath or mantra. Jain “samayika” develops calm balance toward all beings. Sikh “simran” dissolves self-centered thought into deeper awareness.

In the late 20th century, teachers and clinicians began adapting these techniques for secular settings, most notably through mindfulness-based stress reduction (MBSR) and other therapeutic programs. Since then, mindfulness has migrated into psychology, medicine, education, and even corporate wellness.

The Scientific Problem

Here’s where things get complicated. Because different researchers measure different things under the label “mindfulness,” two studies can give very different pictures of what the practice actually does.

Some scientists see mindfulness mainly as attention training—staying focused on what’s happening right now. Others define it in terms of emotional regulation—staying calm when things get stressful. Still others emphasize self-compassion—being kind to yourself when you make mistakes. And some focus on moral awareness—the idea that mindfulness should help people make wiser, more ethical choices.

These differences become obvious when you look at the tests researchers use to measure mindfulness:

• The Mindful Attention Awareness Scale (MAAS) asks about how well someone stays focused on the present moment.
• The Freiburg Mindfulness Inventory (FMI) asks whether a person can notice thoughts and feelings as they come and accept them without judgment.
• The Comprehensive Inventory of Mindfulness Experiences (CHIME) adds something most other tests leave out: questions about ethical awareness and making wise, moral choices.

Why It Matters

This definitional chaos matters for anyone trying to practice mindfulness. If you’re choosing a meditation app or program based on research findings, you might be disappointed. The study you’re relying on may be testing a skill like attention, emotional calm, or self-kindness that isn’t the one you’re hoping to develop.

Without clarity, teachers, doctors, and counselors may not know which approach works best for their goals. The same applies in business for organizational effectiveness and stress management.

The Way Forward

Despite the disagreements, research does show that different forms of mindfulness can produce different kinds of benefits. Practices that sharpen attention to the moment are associated with improved focus and workplace performance. Approaches oriented toward acceptance tend to help people better manage stress, anxiety, and chronic pain. Compassion-based methods can support emotional resilience. Programs that emphasize ethical awareness may promote more thoughtful, prosocial behavior.

For anyone practicing mindfulness, this is a reminder to choose practices that fit your needs. Whether you’re seeking stress relief, better focus, emotional resilience, or ethical growth, understanding how different approaches define and measure mindfulness can help you find the right path.
