This stage encompasses atoms and molecules, the tiny particles that are the fundamental components of all living organisms. A collection of atoms and molecules organizes to form a cell.
A cell is composed of atoms and molecules and serves as the fundamental unit of life.
A tissue consists of a collection of similar cells that collaborate to perform one or more specialized functions.
An organ is a distinct, structured assembly of tissues that function together to perform specific roles within the body.
A system is a collection of interconnected and interdependent organs that collaborate to achieve a particular function or set of functions.
The human organism, the highest level of complexity, is an integrated structure comprising cells, tissues, organs, and systems. Each level is functionally interconnected and crucial for health, as any change in one part affects multiple processes or structures.

, the sweet stage of digestion, begins in (). Here, facilitates the perception of the six rasas (tastes). (elements) of are (earth) and (water). This phase starts as food enters the mouth and mixes with from the three : the , , and . Through —the of food—and by the enzyme , starches are broken down and mixed into a . When food touches the (), taste receptors send signals to the , where processes this perception. initiates and propels the through the into the and via into the (upper stomach). There, initiates the churning process. From here, the sweet taste is yielded into (plasma). The sweet taste is located on the tip of the () and is energetically linked to the and upper . The (post-digestive effect) of (sweet) is (sweet), which is and increases .
amla avastha pāka, the sour stage of digestion, occurs as the food moves into the (). The (elements) of are (earth) and (fire). Here, —manifesting as —secretes and enzymes to initiate protein breakdown and destroy . , a protein-digesting enzyme activated by , is also released. , the protective (), and work in functional integrity to maintain the balance of and protect the stomach wall from acidity. As the is churned into (), facilitates its release in small amounts through the as it is forced against the via into the . This phase releases the (potent energy) of a substance, which is either (warming) or (cooling). From here, the sour taste is yielded into (plasma). The location of the sour taste is on the anterior outer sides of the () and is energetically linked to the . The (post-digestive effect) of (sour) is (sour), which is and increases
, the salty stage of digestion, occurs as moves into the (the first part of the small intestine). The (elements) of are (water) and (fire). This phase begins when opens the , allowing the highly acidic from the to flow into the . Because the entering from the is highly acidic, a large amount of protective to shield its lining. While the secretes small amounts of its own enzymes, the majority of digestion here is performed by enzymes from the and , which enter the through a common . This process is stimulated by two duodenal hormones: triggers the release of and water from the () to neutralize and inactivate , while () stimulates the release of and () from the and . facilitates the linear movement that pushes the forward and regulates the water-electrolyte balance. From here, the salty taste is yielded into (plasma). The location of the salty taste is on the posterior outer sides of the () and is energetically linked to the . The (post-digestive effect) of (salty) is (sweet), which is and increases .
, the pungent stage of digestion, occurs primarily in the (the second segment of the small intestine). The (elements) of are (air) and (fire). This phase is governed by the functional integrity of and . During this hour, the predominant intestinal enzymes exhibit pungent properties, facilitating the ongoing chemical breakdown of macronutrients, including proteins, fats, and carbohydrates. The fire element inherent to this stage enhances and increases blood circulation within the , promoting optimal enzymatic activity and turning the yellowish-brown. Simultaneously, the air element produces gases and stimulates intestinal via , which is essential for the effective propulsion of digestive contents. While most absorption occurs in the and , the serves as the major site for the initial absorption of . From here, the pungent taste is yielded into (plasma). The location of the pungent taste is on the central part of the (), positioned in front of the bitter area, and is energetically linked to the , , and . The (post-digestive effect) of (pungent) is (pungent), which is catabolic and increases .
, the bitter stage of digestion, occurs as progresses into the (the terminal and longest segment of the small intestine). The (elements) of (bitter) are (air) and (ether). This phase is characterized by the continued stimulation of , which maintains necessary for the efficient transit and rapid absorption of through the intestinal . This stage exerts a systemic cooling effect on the body, helping to alleviate symptoms associated with elevated . From here, the bitter taste is yielded into (plasma). The location of the bitter taste is on the central part of the (), positioned behind the pungent area, and is energetically linked to the , , and . The (post-digestive effect) of (bitter) is (pungent), which is and increases .
, the astringent stage of digestion, is the final phase occurring in the (). The (elements) of are (air) and (earth). This process begins when and open the , allowing to enter the . Within the , governs the movement of material through the , , , , and . During this phase, the remaining water, minerals, and electrolytes are absorbed into the system. The earth element provides the roughness and bulk necessary to compact waste material into well-bound feces () in the and . This stage stimulates mass , and the air element nourishes to facilitate the urge to defecate. The process culminates as the downward and outward energy of propels the waste through the and for elimination at the . Following this elimination, the air element stimulates in the hunger center of the brain, signaling the return of true appetite and the activation of . From here, the astringent taste is yielded into (plasma). The location of the astringent taste is on the posterior part of the () and is energetically linked to the . The (post-digestive effect) of (astringent) is (pungent), which is and increases .
is the Ayurvedic principle of mobility that regulates all activity in the body and mind, from the flow of thoughts to the movement of food through the intestines. It is considered the most important dosha because it governs all biological movement and carries the other two doshas throughout the body. It is primarily composed of the Ether (Space) and Air elements.
The physical form () of a Vāta individual is typically:
is the Ayurvedic principle of transformation that regulates metabolism, digestion, and the conversion of energy throughout the body and mind. Primarily composed of the Fire and Water elements, it manifests as the heat and biochemical actions required for life.
The physical form () of a Pitta individual is generally balanced and moderate:
is the Ayurvedic principle of structure and lubrication that gives the body physical form, cohesion, and stability. It is the “glue” that holds the cells together and supplies the water for all bodily systems and joints. It is primarily composed of the Water and Earth elements.
The physical form () of a Kapha individual is typically large and well-developed:
