Speech: The Power of Words

As important as intentions are in themselves, they are by nature a starting point designed for follow through. James 2:26 in the New Testament declares: “For just as the body without the spirit is dead, so faith without works is also dead.” Just so, intentions without expression are unfulfilled, and maybe, eventually toxic. The fulfillment of intention comes in two forms: speech and action. Speech is the beginning of embodiment, transforming the invisible to the visible. It is the bridge between the internal realm of consciousness and intention and the external realm of behavior and action. Deservedly, speech plays a vital role in many spiritual traditions.

In the Abrahamic traditions, virtually the entire creation story in Genesis is centered on three words, “And God said,” as the means of creation. In addition to God’s speech being His method of creation, He used them in another powerful way: “God blessed them and said to them, ‘Be fruitful and increase in number; fill the earth and subdue it. Rule over the fish in the sea and the birds in the sky and over every living creature that moves on the ground.’” (Genesis 1:28) God’s speech here is not just the kind of blessing we usually associate that word with—it confers favor, imposes duty, and issues a command, all at once.

While Genesis (and the corresponding creation story in the Qur’an) focus on divine speech, the Abrahamic sacred texts also have much to say about human speech. For the Jews, we can point to the simple commandment, “You shall not bear false witness against your neighbor.” (Exodus 20:16) Note the central importance of the social connection implied here. In Islam, speech is not only an action, but also a moral artifact. Every word is seen as an act recorded, and with spiritual consequences. Qur’an 50:18 says, "Not a word does one utter, but there is a watcher by him ready to record it." Honest speaking reflects divine submission, and in fact it is divinely commanded. “O believers! Be mindful of Allah and say what is right. He will bless your deeds for you and forgive your sins.” (Qur’an 33:70) But the Judeo-Christian-Islamic faiths are far from alone in recognizing the crucial importance of speech.

The brilliant Roberto Calasso, in his masterwork Ardor, reminds us of the role of attuned speech through the Vedic concept of Vāk.³⁸ Vāk is not just any human speech; it is the cosmic principle of utterance, the word as power. It is itself an offering – it is the enactment or declaration of intention. The Vedic mantras are likewise not merely prayers. They are the ritual technology that aligns human consciousness with cosmic order (in other words, they are one strategy for forming intentions). Calasso wrote, "vāk is the closest the human gets to touching the real", because it is the moment where formless thought is given form—but before it is fixed in action. It is worth noting that vāk is the etymological ancestor of the Latin vox, and modern words like vocal and invoke. The reminder that speech is powerful is embedded even in our language.

Where vāk names the sacred power of utterance, Right Speech in Buddhism is a discipline for speech in service of a practical ethics. The core guidelines for Right Speech are to shun deception, divisiveness, harshness, and idle chatter (including gossip). But these are not simply rules or commandments. It is to align speech with some specific intentions: clarity, compassion and awareness. Speech is a tool to reduce suffering and attain liberation, as the third step of the Eightfold Path.

Scientific evidence supports the weight given to speech by these (and other) spiritual traditions. In fact, the science indicates that speech can influence both action and internal states like thoughts and feelings. For example, self-affirmation exercises improve problem-solving performance under stress among chronically stressed individuals.³⁹ And labeling emotions aloud (e.g., saying, “I feel angry) activated the right ventrolateral prefrontal cortex (which can help dampen emotional reactivity) and reduced activity in the amygdala (which processes emotional intensity, especially from fear, anger and threat), leading to decreased emotional intensity.⁴⁰

Any externalization of speech, written or vocalized, heavily influences action as well. A review of the literature from 2019 in BMC Public Health analyzed multiple randomized trials to see if adding formal commitment contracts (pledges or agreements to change behavior, usually either written or spoken aloud) improves outcomes in weight loss programs. This review covered 10 studies of adults who were overweight or obese, who underwent lifestyle interventions, some of which included commitment techniques (like signing a “contract” or publicly pledging goals). Their findings showed that those who made such a commitment lost about 3.3lbs more in the short term than their cohort. Importantly, these committers slightly extended their advantage over the control group over time: at 12-month follow ups, they had maintained an extra 3.7lbs of weight loss over the control group. Poignantly, the most effective way of stating intention was public and more specific.⁴¹ These public pledges function as secular versions of the Vedic mantras – spoken offerings that align personal will with an intended outcome. Vāk finds a subtle echo here: speech as the enactment of intention, not just its announcement.

Analogous results were found in the context of drug abuse in a foundational, peer-reviewed study by Amrhein et al in 2003. This study analyzed taped sessions of 84 individuals undergoing therapy for drug abuse, noting each instant where clients verbalized commitment, desire, ability, need or reasons for change. Twelve months later, the results were clear: the stronger and more frequent clients’ commitment statements were during sessions, the more likely they were actually abstinent thereafter over that next year.⁴²
