Dosha Gati means movement or status of Doshas. Movement of Doshas from their places to others causes diseases. It is also a form of Dosha vitation which is the prime contributory factor for causation of diseases.
There are many types of dosha movements. Here, in this context we would be discussing about the dosha movements which occur due to the impact of seasonal changes i.e. chaya, prakopa and prashama of doshas.

Chaya, Prakopa, Prashamana of Doshas
Chaya (Sanchaya) means accumulation of doshas in their own seats
Prakopa (Kopa) means aggravation of doshas in their own seats and
Prashamana (Shamana) means auto-pacification of doshas.
Chaya, Prakopa and Prashamana are considered as dosha movements occurring in different seasons due to weather changes. This is also called as Rtu Kriya Kala or Dosha Kriya Kala

In the stage of accumulation of Dosha (chaya or sanchaya stage), the doshas tend to accumulate in their chief seats.
In the following season the dosha accumulation further progresses and the dosha gets aggravated in its own seat (prakopa).

If the Rtucharya i.e. seasonal regimen is followed correctly, the doshas pacify by themselves in the upcoming season (shamana) and do not progress to the next stages of disease manifestation and hence, they do not cause diseases.
On the other hand, if the Rtucharya is not followed correctly, the doshas instead of undergoing auto-pacification will progress through the next stages of pathogenesis –
i.e. Prasara (stage of spread of doshas in all parts of body),
Sthana Samshraya (localization of vitiated doshas in tissues leading to their damage and production of purvarupas or premonitory symptoms of disease),
Vyakta (manifestation of disease and its signs and symptoms) and
Bheda (stage of complications).
Example, Kapha sanchaya takes place in Shishira Rtu or late winter.
Kapha gets accumulated in its own place in later winter.
In the following season i.e. spring season, kapha prakopa (excessive acumulates excessively in its own place).
If seasonal regimen are followed in later winter and spring seasons, then Kapha gets pacified naturally in the next season – Grishma Rtu or summer season. So, Kapha unders pacification (Prashama) in summer season, naturally.
If Ritucharya is not followed, the kapha instead of getting pacified (prashamana) will progress to other stages of pathogenesis (samprapti or kriya kala) i.e. prasara (stage of spread), sthana samshraya (lodgment of dosha in dhatus or tissues), vyakta (manifestation of disease) and bheda (formation of complications).
This kapha, instead of undergoing auto-pacification will progress to form the diseases, mainly kaphaja diseases in future time.
For a better understanding of these gatis the topic of ‘Kriya Kala’ should give a better clarification.
Importance of having the knowledge of Chaya, Kopa and Shamana of doshas
It is very important that a physician has a thorough knowledge of these gatis of the dosha. The knowledge of these gatis would help a physician to know the quality and quantity of vitiation of doshas and also the progression of the dosha vitiation and try to implement interventions as soon as possible. When the dosha vitiation is controlled at the earlier stages it doesn’t progress to the next stages of pathogenesis and hence the disease process is aborted at the earliest.
Just Before Finishing –
In this article we have discussed about chaya, prakopa and shamana of doshas in terms of these statuses of doshas being dosha gatis which are responsible for dosha dushti and for manifestation of diseases.
