A **Svakshetra Parivartan** is a period of time during which a being can hold as many **Avgahnas** as possible until reaching the **Utkrishta Avgahana**.
**Parakshetra Parivartan**: A being holding a **Jghanya Avgahana**, a **Sukshm Nigodhya Labya Paryaptak Jiva**, is born in the **Asta Madhya Pradesh** of the **Sudarshan Meru**, below the **Achal Roop** of the **Lok**, making it their body. Later, the same being is born again in the same place, in the same form, for a second or third time. In this way, the being is born in the same place, in sequence, as many times as there are **Pradesh** of the **Jghanya Avgahana**, which is a fraction of the **Ghanangal**. The being then experiences **Kshudra Aayu**, which is one-eighteenth of a **Shwas**, and dies. Later, the being takes birth in the entire **Lok**, in sequence, over a period of time, which is equal to the number of times the being is born in each **Pradesh**. This period of time is called a **Parakshetra Parivartan**.
**Question**: What is **Kal Parivartan**?
**Answer**: A being is born for the first time in the first **Samay** of the **Utsarpini**. Similarly, the being is born for the second time in the second **Samay** of the second **Utsarpini**. In this way, the being is born in sequence, in all the **Samay** of the twenty **Koda Kodi Sagar** of the **Utsarpini** and **Avasarpini**. The being then dies in the same sequence.
