The Yagya Shala has been designed according to Vedic guidelines and houses the Havan Kund (fire pit). This is an outside structure, near the Student Union, where Sri Somesvara Havans are generally performed.
Since it has a brick and cement floor, it is a good idea to bring something to sit on. It is also advised to dress appropriately for the weather since it is predominantly open to the elements.
Guidelines for the Yagya Shala are similar to guidelines for Sri Somesvara Temple. Go to the Temple Etiquette page for more information.
