Proprioception + interoception
1. Choose a position you feel comfortable in.
2. Bring your awareness to the field of your body. Notice the state it’s in at the moment, as well as the shifts that may occur. Notice which senses you use to sense yourself. Notice what is in the background, and what in the foreground of your perceptual awareness.
3. Continue moving your awareness across the field. Listen to the stimuli and the impulses that arise from within. You can move or touch yourself if it feels enabling. See if your perception or sense of the field shifts as you move.

Extended proprioception + interoception
1. Shift your awareness to the space and the bodies around you. > Expand your sense of self (the interoceptive field) into the space around you.
2. Bring your awareness to a neighboring body and observe it as if it were yours, or a part of your body > sense it from the “inside” rather than “outside”. Become the other’s self-sensing organ. (You can use the means that are available to you at the moment – you can open your eyes if needed, approach the other body, sense into it with your hands, etc. You may even include touching if it comes naturally.)
3. Expand your awareness to the whole group. Continue doing the same you did before.
4. Go outside; do the same with a nonhuman body. (This can be done alone or in a group.)

Proprioception (/ˌproʊpri.ɵˈsɛpʃən/ pro-pree-o-sep-shən), from Latin proprius, meaning “one’s own”, “individual,” and capio, capere, to take or grasp, is the sense of the relative position of neighbouring parts of the body and strength of effort being employed in movement. In humans, it is provided by proprioceptors in skeletal striated muscles (muscle spindles) and tendons (Golgi organs) and the fibrous capsules in joints. It is distinguished from exteroception, by which one perceives the outside world, and interoception, by which one perceives pain, hunger, etc., and the movement of internal organs. The brain integrates information from proprioception and from the vestibular system into its overall sense of body position, movement, and acceleration. The word kinesthesia or kinæsthesia (kinesthetic sense) strictly means movement sense, but has been used inconsistently to refer either to proprioception alone or to the brain’s integration of proprioceptive and vestibular inputs.

Humans have a multitude of senses. Sight (ophthalmoception), hearing (audioception), taste (gustaoception), smell (olfacoception or olfacception), and touch (tactioception) are the five traditionally recognized senses. The ability to detect other stimuli beyond those governed by these most broadly recognized senses also exists, and these sensory modalities include temperature (thermoception), kinesthetic sense (proprioception), pain (nociception), balance (equilibrioception), vibration (mechanoreception), and various internal stimuli (e.g. the different chemoreceptors for detecting salt and carbon dioxide concentrations in the blood).

Nociception (physiological pain) signals nerve-damage or damage to tissue. The three types of pain receptors are cutaneous (skin), somatic (joints and bones), and visceral (body organs). It was previously believed that pain was simply the overloading of pressure receptors, but research in the first half of the 20th century indicated that pain is a distinct phenomenon that intertwines with all of the other senses, including touch. Pain was once considered an entirely subjective experience, but recent studies show that pain is registered in the anterior cingulate gyrus of the brain. The main function of pain is to attract our attention to dangers and motivate us to avoid them. For example, humans avoid touching a sharp needle, or hot object, or extending an arm beyond a safe limit because it is dangerous, and thus hurts. Without pain, people could do many dangerous things without being aware of the dangers.

An internal sense also known as interoception is “any sense that is normally stimulated from within the body”. These involve numerous sensory receptors in internal organs, such as stretch receptors that are neurologically linked to the brain. Some examples of specific receptors are:
Hunger (motivational state) defined in humans, in the past as an aspect of lust. This sense comes from three of the five classic senses combined or separate, sight, smell and taste.
Pulmonary stretch receptors are found in the lungs and control the respiratory rate.
Peripheral chemoreceptors in the brain monitor the carbon dioxide and oxygen levels in the brain to give a feeling of suffocation if carbon dioxide levels get too high.
The chemoreceptor trigger zone is an area of the medulla in the brain that receives inputs from blood-borne drugs or hormones, and communicates with the vomiting center.
Chemoreceptors in the circulatory system also measure salt levels and prompt thirst if they get too high; they can also respond to high sugar levels in diabetics.
Cutaneous receptors in the skin not only respond to touch, pressure, and temperature, but also respond to vasodilation in the skin such as blushing.
Stretch receptors in the gastrointestinal tract sense gas distension that may result in colic pain.
Stimulation of sensory receptors in the esophagus result in sensations felt in the throat when swallowing, vomiting, or during acid reflux.
Sensory receptors in pharynx mucosa, similar to touch receptors in the skin, sense foreign objects such as food that may result in a gag reflex and corresponding gagging sensation.
Stimulation of sensory receptors in the urinary bladder and rectum may result in sensations of fullness.
Stimulation of stretch sensors that sense dilation of various blood vessels may result in pain, for example headache caused by vasodilation of brain arteries.

Other animals also have receptors to sense the world around them, with degrees of capability varying greatly between species. Humans have a comparatively weak sense of smell relative to many other mammals while some animals may lack one or more of the traditional five senses. Some animals may also intake and interpret sensory stimuli in very different ways. Some species of animals are able to sense the world in a way that humans cannot, with some species able to sense electrical and magnetic fields, and detect water pressure and currents.


Circles of listening
1. Listen to the sounds that are closest to you, include the sounds within your own body.
2. Expand the circle of listening by including sounds that are further and further away from you. What is the furthest sound you can hear? If you try to listen beyond it, what do you hear?
3. Try to hear all the sounds at the same time. Try to not name them or distinguish them from each other.
4. Notice what you are leaving out (or not hearing).

Zooming / Telescoping Awareness
1. Zoom in on a little detail, and listen to it as closely as you can.
2. Move back to hearing everything at the same time. Move between these two modalities or ranges.
3. Allow the listening to move you in the landscape.

Virtuaaliset äänet
1. Laajenna kuulemistasi kuultavien/konkreettisten äänien ulkopuolelle. Miten voit kuunnella ääniä, joihin kuuloaistisi ei yllä? Ne voivat olla esim. liian hiljaisia, liian kaukaisia tai muutoin kuulemattomissa.
2. Laajenna kuuloa tilassa ja ajassa. Miten voit kuunnella tilallisesti äärimmäisen kaukaisia tai laajoja ääniä, esim. ilmastonmuutoksen tai sään ääntä? Miten voit kuunnella maan geologisten kerrosten ääniä? Entä avaruuden ääniä? Kuinka kauas galaksiin voit kuulla?
3. Ajallinen laajentaminen historiaan ja tulevaisuuteen. 10000 vuotta taaksepäin ja eteenpäin. Pyri kuulemaan kaikki nämä ajat samanaikaisesti.
