The ability to stop the internal dialogue is a key condition for any spiritual practice. Internal dialogue is present in every person’s head. It keeps in place the picture of the world that society installed in early childhood.
What does the internal dialogue look like? In consciousness there is a constant spontaneous movement of thoughts, the so-called mental noise. Even a glance at an object starts associative chains, and thinking about nothing begins. A person thinks, sorts through options, reasons, runs through situations. The output is zero. Even the reason for the activity is lost within a second, and the thought goes nowhere. It resembles aimless chatter in a large room of near-strangers.
Try not to think about anything for at least twenty seconds. Without preparation, and without straining on the thought “I must not think.” After twenty seconds you will find that the thinking process never left. It ran the whole time you were “not thinking.” In most cases the internal dialogue is also duplicated by articulation. You can notice the involuntary voicing of thoughts, accompanied by tiny movements of the tongue and lips.
To begin, step a little aside from your consciousness and, from the position of an outside observer, try to catch the moments when new thoughts arise. It also helps to catch the points where one thought passes into another. Almost all techniques for stopping the dialogue rest on a clear sense of how it works, and on the ability to notice unwanted thoughts as they appear.
External conditions matter too. A separate room with as few irritants as possible — light, noise, voices — is useful. You will not be distracted, and the spontaneous work of the dialogue is easier to see when there is no obvious reason for a thought to start.
A horizontal position is preferable. Then relax, using whatever methods you have, and set the intention to practice. The easiest time is in the morning, right after waking. The most effective time is before sleep.
First method. Move into the state of the “observer” and perceive your consciousness from a distance, tracking the appearance of spontaneous thoughts. When they appear, extinguish them with a soft push of consciousness. Do not turn the act of noticing or extinguishing into a thought of its own.
Thoughts such as “a thought appeared — now I will stop it” are also internal dialogue. What should be working is intention and the setting you gave yourself beforehand. It is worth learning to stay in this inner silence for at least three or four minutes. After that, a shift into an altered state is possible, and the silence begins to hold itself.
After you have reached that silent state many times, it makes sense to treat it as a beacon and to develop a code phrase associated with it. Using the phrase, you will reach inner silence noticeably faster.
Second method. Focus consciousness on a monotonous mental task that occupies the whole field of attention. Create the thought-form of a blue cube. The cube rotates slowly. The main thing is never to let it leave attention, and not to lose the settings of the form: color, size, shape, smoothness of rotation. This way can also bring the needed state.
Third method. The simplest and the hardest at the same time. The internal dialogue is stopped by will. You simply make the inner voice be quiet. With a developed will, it can work.
Fourth method. In rhythm with the breath, count silently from 1 to 100. If even one outside thought appears during the count, start again. Continue until you get the result. Then you can raise the count to 200, and further. The outcome should be a silence that no longer needs effort to maintain.
Fifth method. You can use the Zen practice of illogical, paradoxical images — the koan. Many can be found online. By concentrating the mind on a koan, you drive it into a kind of stall. With enough concentration, there should be no outside thoughts.
All the previous techniques asked for specific conditions: silence, solitude, and so on. How do you stop the internal dialogue in the middle of a full day?
Almost all of our actions are done automatically, without the area of conscious thinking. Repeated day after day, they become habits, carried out by the subconscious. The freed energy of consciousness needs an outlet. The internal dialogue, besides locking us into the existing agreement about the world, is busy “using up” that energy. Otherwise, unrealized energy can feed nervous strain and wear at the familiar picture of the world.
A natural solution is to remove habits from life where you can. Change the ordinary order and the way you do things. Start with the most automatic ones. Tie your laces with a different knot. Brush your teeth with the other hand, and differently. Rearrange the things on your desk. Find a new way to get to work.
In principle, if the hands or feet want to perform an action by themselves, that is a habit you can change. A consciousness occupied with the work leaves the internal dialogue without fuel. Gradually the habit of a constant mental background fades too. The main point of this practice: while dropping some "household rituals," do not create new ones.
There is another option. You do not have to abandon the familiar pattern. You can stay in the state of the “observer” and watch the habits from a distance as they are carried out. This way of stopping the internal dialogue is fairly difficult and needs a good skill of concentration.
