As living body is also one object in the universe; Lok (universe) and Purusha (Person) are similar. This statement is important to know about purusha(person) from the study of universe. Also all the chemical and physical laws are equally applied to external objects and in human body. In human body, just with a little modification; due to the presence of mind, intellect and sprit in man. (dhee, dhriti, smriti) .
Aacharya Charak in his “Shareer sthan” of Charak Samhita purusha vichaya chapter gives a list of similarities in between man and world.
In Lokasamhita Acharya Punarbashu (Aatraya) said all the factors (bhawas) that are present in person (purusha) or human body are represented in the universe and vice versa. Hearing this Shri-Agnivesha asked Acharya Aatraya to elaborate the statement. Then Acharya Atraya replied “This cosmos prapancha is made up of 6 dhatus/elements i.e. Panchamahabhootaj and chetanadhatu.
