Taking control of our emotions is key to improving our happiness.

This can be a learned skill, using mantras, meditation and hypnotherapy.

These are altered states of consciousness, access to which enable us to change our subconscious mind, and so, our thoughts.

Mantras and the Science behind their Efficacy


In the realms of spirituality, wellness, and mental health, mantras have been utilised for thousands of years, originating from ancient traditions such as Hinduism and Buddhism. A mantra is a syllable, word, or phrase that is repeated during meditation or prayer, often silently. These sacred utterances are believed to possess psychological and spiritual power, but what does contemporary science say about why and how they work? This essay explores the scientific underpinnings of mantras, supported by examples, to understand their efficacy from a modern perspective.

 The Psychological Impact of Repetition

Repetition is a fundamental element of mantra practice, creating a focal point that helps in reducing the stream of thoughts that usually invades the mind. This concept is supported by research in cognitive psychology, which suggests that repetition can enhance cognitive performance, including memory and attention. By focusing on a mantra, individuals can achieve a state of deep concentration, reducing stress and enhancing overall mental clarity. For example, the "So Hum" mantra, which translates to "I am that" in Sanskrit, is used in meditation to help individuals focus on their breathing and achieve a deeper state of awareness and self-connection.

The Neurophysiological Effects 

The repetitive nature of mantra chanting has been shown to positively affect the brain's neurophysiology. Neuroimaging studies reveal that mantra meditation can lead to changes in brain regions associated with attention, emotion regulation, and self-awareness. Specifically, the practice can decrease activity in the default mode network (DMN), a network of brain regions active during mind-wandering and self-referential thoughts often associated with anxiety and depression. This suggests that mantra practice can lead to a more present, less anxious state of mind. The mantra "Om Mani Padme Hum," for instance, is believed to transform negative emotions into positive virtues, a transformation that could be supported by its calming effect on the brain.

The Role of Sound and Vibration

Mantras are often chanted aloud, and the vibratory quality of sound is said to have healing properties. From a scientific viewpoint, sound vibrations can influence the body's release of hormones and neurotransmitters that regulate physiological processes. The vibration of chanting can stimulate the vagus nerve, which runs from the brain through the neck to the abdomen, playing a significant role in calming down the nervous system. This can explain the profound sense of peace and well-being reported by practitioners of the "Om" chant, one of the most universally recognized mantras, symbolising the sound of the universe.

Examples of empowering mantras might include:-

“Today you are perfect” - for building self-confidence.

“Forward progress! Just keep moving!” - for strength and will-power.

“I am attracting all the love I dream of and I deserve” - for manifesting love.

“I am strong. I am beautiful. I am enough”- for building self-esteem.

“I am fulfilled. I am fearless” - for starting the day.

Decide on the changes you wish to make to your subconscious, and write down a mantra to embody those.

Psychological Conditioning and the Placebo Effect 

The effectiveness of mantras can also be partly attributed to psychological conditioning and the placebo effect. When individuals believe in the power of a mantra to bring about positive change, this belief can itself trigger a physiological response that aligns with their expectations. The consistent use of a personal mantra, such as "I am calm and in control," especially in moments of stress or anxiety, can condition the mind to associate the mantra with a state of tranquillity, thereby making it a self-fulfilling prophecy.


The efficacy of mantras is not merely a matter of faith or ancient tradition; it is increasingly supported by scientific evidence. The psychological impact of repetition, neurophysiological effects, the role of sound and vibration, and the mechanisms of psychological conditioning and the placebo effect all contribute to why mantras work. Whether it's the profound peace invoked by chanting "Om" or the self-empowerment fostered by personal affirmations, the science behind mantras reveals a fascinating intersection of spirituality, psychology, and neuroscience, offering a valuable tool for enhancing mental health and well-being.
