The importance of 'Swaha' during Yagna and hawans

Some of the most common fire rituals, that every Hindu knows of and has performed at some point in life, are Hawans and Yagna. In these, Hawans are more common and are performed on smaller scales with family while the Yagnas are much more grand and bring together communities. In the past, Kings and rulers used to perform Yagnas for prosperity, health, or security, and more, and today, Hindus perform Hawans to purify the household, ask for blessings, and the likes.
