Lung (Tibetan Buddhism)

• 1. Introduction

  ›

  Lung, written in Tibetan as rlung, is the word for wind or breath, but in Tibetan Buddhism it carries a weight far beyond its translation. It sits at the center of how practitioners understand the body, the mind, and the invisible architecture that holds them together. Traditional Tibetan medicine practitioner Tamdin Sither Bradley describes it plainly: rlung is a subtle flow of energy, most closely connected with the element of air out of the five elements, air, fire, water, earth, and space. Yet it is not simply the air we breathe or the wind in our stomachs. Something else is happening at a deeper level. Bradley offers a metaphor that opens the whole subject: rlung is like a horse, and the mind is the rider. If something is wrong with the horse, the rider cannot ride properly. That image is deceptively simple. It raises the question of what happens when rlung falls out of balance, and what practices exist to bring it back. It also raises a larger question: how does a single concept stretch across medicine, yoga, prayer flags, and the transmission of spiritual power from master to student?

  Tamdin Sither Bradley lists qualities of rlung in precise terms: it is rough, light, cool, thin, hard, and movable. Its nature is both hot and cold simultaneously, a paradox that signals something outside ordinary categories. The term lung does not belong to one domain. In Vajrayana yoga practices, it names the psychic winds, known in Sanskrit as prana, that travel along invisible internal channels called nadi within the subtle body. Those winds are manipulated directly in certain tantric exercises. At another register, lung refers to five specific psychic winds that are the life force animating the bodymind of all sentient beings, the Sanskrit term being namarupa. These five are central to both tantric Buddhist and Bon sadhanas and to traditional Tibetan medicine. Lung also connects to the vayu and prana concepts found in ayurveda, the classical Indian medical tradition. One of the most visually familiar uses appears in the name for a type of prayer flag: lung ta, meaning Wind Horse, an allegorical figure whose name carries the lung concept into textile and public devotion. Then there is a meaning that cuts to the heart of how Vajrayana transmits itself. Lung names a type of tantric empowerment in which a teacher transfers spiritual power to a student through the recitation of scripture or song. That oracular transmission, received aurally, is what defines the Vajrayana and Ngagpa traditions and gives them their very names. A related but distinct use is the reading transmission of sutrayana texts, where the teacher reads the entirety of a text aloud to the student, mouth to ear, completing a chain of living transmission.

• 3. The Five Lungs of the Body

  ›

  Traditional Tibetan medicine, practiced throughout the Himalayas, maps the human body through a system called the Five Lung. Each of the five has a location, a name, and a specific set of functions that read like a carefully observed anatomy of inner life. Life-grasping lung, srog 'dzin rlung in Tibetan, is located in the brain. Its work is to regulate swallowing, inhalation, sneezing, spitting, eructation, and the clearing of the senses; it also steadies the mind and concentration. Upward moving lung, gyen-rgyu rlung, is seated in the thorax. Its reach is wide: it governs speech, the energy needed to work, body weight, memory, bodily vigor, complexion, and the lustre of the skin, as well as mental endeavor and diligence. All pervading lung, khyab-byed rlung, is located in the heart and manages physical movement, including lifting, walking, stretching, the contraction of muscles, and the opening and closing of the mouth, eyelids, and anus. Fire accompanying lung, me-mnyam rlung, sits in the stomach and abdomen and governs digestion and metabolism. It is also said to ripen what the tradition calls the Seven Bodily Sustainers, lus-zung dhun in Tibetan. Downward cleansing lung, thur-sel rlung, is located in the rectum, gastrointestinal tract, and perineal region, and its function is the expulsion of feces, urine, semen, menstruation, uterine contractions, and the fetus. This last lung is also designated by most sublime Vajrayana practices as "enjoyment lung," with the note that direct transmission from a qualified teacher is required to work with it.

• 4. The Subtle Body and Its Winds

  ›

  Tibetan Buddhism holds that the human person is not one body but two running in parallel. There is the coarse body, composed of six constituent elements: earth, water, fire, wind, space, and consciousness. Alongside it is the subtle body, called the Vajra body, built of winds, channels, and drops. Many types of subtle breath move through the invisible channels of that body. Among them, the vital breath, sog lung in Tibetan, is considered the most important. It is described as the essence of life itself, the force that animates and sustains all living beings. Anuttarayoga Tantra practices within the Mahamudra meditation system offer specific methods for working with those vital points of the subtle body. Texts that belong to this tradition include the Guhyasamaja, Cakrasamvara, and Hevajra tantras. The 14th Dalai Lama has summarized what penetrating those vital points actually means: "To penetrate these points means to gather there the energy-winds and the subtle minds that ride on them, basically by means of different types of absorbed concentration focused on these spots." One of the most direct practices for working with the subtle winds is tummo, known as Inner Fire, which is one of the Six Yogas of Naropa. In tummo, the practitioner uses breathing and meditation techniques to draw lung into the central channel, which traverses the body vertically, and to hold the winds there.

• 5. Tsalung and Sacred Architecture

  ›

  Tsalung is the name for a category of special yogic exercises. The Tibetan spelling is rtsa rlung, and the Sanskrit equivalent is nadi-vayu, where rtsa denotes an energetic channel. These exercises are practiced in the Bon tradition and across all four main schools of Tibetan Buddhism. Trul khor, a Tibetan yoga system, employs tsa lung as what the tradition calls the internal yantra, or sacred architecture, of that practice; the Sanskrit name yantra yoga reflects exactly this interior structural quality. Tsa lung exercises also appear in generation stage practices, which are foundational to certain tantric approaches to meditation. The continuity of lung as a concept across Bon and the four main Tibetan Buddhist schools points to how deeply embedded it is in the broader Himalayan contemplative inheritance, appearing not as the property of one lineage but as a shared operating principle of the tradition's understanding of mind and body.
