Explanation:

- Antarala: This is the small vestibule or intermediate chamber connecting the sanctum (garbhagriha) with the temple hall or mandapa. It doesn't refer to any disc or rooftop structure.

- Jagati: This term refers to a raised platform or terrace on which the temple is built, not a feature located at the top.

- Amalaka: This is a stone-like disc, often ribbed, that is seen crowning the top of the temple tower (shikhara). It symbolizes the celestial seat and is commonly seen in the Nagara style of temple architecture in Odisha and nearby regions.

- Kalasha: This is the pot-like finial placed above the Amalaka, often seen as a sacred symbol.
