#In the process of ''avarana chala'' property of ''vata'' is diminished due to obstruction. Other properties are not involved in the process of obstruction. But in case of ''gatatva'' the vitiation of ''vata'' takes place by involvement of other properties like ''ruksha, laghu, khara, vishada'' etc along with ''chala''.

#In ''avarana'' the ''gati'' of ''vata'' is obstructed partially or fully. Once gets obstructed the ''vata'' may simply get lodged there (''baddha marga, margarodha''), try to nullify the obstruction, may get covered by the obstructing substance (''avrita''), adopt an opposite direction (''pratiloma'') or alter the direction (''viloma''). The different terminologies have been used to denote ''avarana'' in different contexts according to the nature of ''avarana'' and the state of ''vata'' and ''marga'' (passage). In case of ''gatatva'' the ''gati'' of vitiated ''vata'' aggravated and starts moving abnormally leading to localization at particular sites.''Avarana'' is caused by ''purnata'' (filling) of other ''dosha'' in the ''srotas/marga'' (passage) of ''vata''. In ''gatatva'' the ''srotas'' or sites of occupation of ''vata'' are ''rikta'' (unfilled or spacious) and the aggravated ''vata'' fills the ''srotas''/site.

#In ''avarana'' of ''vata, swakarma vriddhi'' (exaggerated activities) of ''avaraka'' (covering ''dosha'') is manifested. The ''avrita'' (i.e. ''vata'') will show ''swakarma hani'' (diminished activity). This is the general feature of ''avarana''. Here the excessively increased strong ''avaraka'' suppresses the normal action of ''avrita'' (i.e. ''vata''). Therefore, when the obstruction is complete it may lead to the ''prakopa'' of ''vata'' resulting in the presentation of ''vata'' vitiated symptoms as well as its disorders[ Cha. Sa. Chikitsa Sthana 28/215, Chakrapani]. In case of ''gatatva'' the symptomatology will be predominantly of ''vata'' vitiation and pain is a common and chief complaint in all the conditions of ''gatatva''.

#Obstruction or covering of ''vata'' is possible by body components like ''dosha'' (''pitta'' and ''kapha''),tissues,food,  excretory products or mutual affliction of ''vata'' types. ''Gatatva'' of ''vata'' (affection) is happening in empty spaces or hollow cavities of tissues, their elements, organs and other body parts. In ''avarana'', the body component is in increased state causing fullness in respected channels, while in ''gatatva'' pathology, the body components are in depleted state casusing emptiness in the respected channels. ''Dhatugata vata'' will be presented with decreased quality of tissues associated with signs of vitiated ''vata''. Obviously, exceptions are possible according to the complexities of process of ''avarana'' or ''gatatva''.

#In case of ''avarana'' of ''vata'', the ''avaraka'' is important for  treatment since vitiation of ''vata'' is passive. When ''avarana'' is removed vitiated ''vata'' gets pacified. But in cases of ''gatatva'', the vitiated ''vata'' has to be treated first along with correction of ''adhisthana''.
