Following from above, the basic form of cosmological space is the sacrificial arena. However, many of the Vedic gods, such as Agni, the fire god, have three different forms corresponding to the three Vedic realms. These "realms" are not only spatial but can also be described as mental states of mind: loka, or world, in its earliest meanings, can mean the "freedom to exist unimpeded" or "expansiveness" as much as it can mean a physical location. Yet these three realms are not the only form of imagined space: at death, the Vedic funeral hymns assert, the various elements within a person are scattered to various parts of the natural world. Alternatively the person can go to the realm of Yama, the overlord of the dead.
