Meditating naturally involves embracing silence.
To fully focus our attention on our senses—our eyes, ears, nose, mouth, and body—distractions from external stimuli must be minimized.
Speaking, for instance, involves reacting to a stimulus, which generates thoughts and creates additional distractions.
Meditation can be compared to gently descending beneath the surface of calm water.
Speaking, however, is like throwing a stone into the water, creating ripples that disrupt the stillness.
As a result, the consciousness, which was gradually sinking into deeper states of awareness, rises and scatters across the surface.
This is why silence is essential during meditation.
While making simple non-verbal sounds can sometimes be incorporated as a useful meditation technique, the act of speaking itself disrupts the meditative state.
Even so, observing the act of speaking—focusing on the opening of the mouth, the flow of air, and the vibration of the vocal cords—can offer meditative insights.
However, reaching a truly deep meditative state necessitates silence.
Ultimately, meditation is about constantly observing and nurturing our mind.
If we create external noise when we should be listening to our inner voice, we risk drowning out the sound we truly need to hear.
