Vedic Cosmology

Cosmology is defined as the study of the origin, purpose, structure and functioning of the universe. Vedic cosmology gives a vast amount of information about not only the structure of the phenomenal universe as we see it, but also a clear idea of the source of the manifested universe, its purpose, and the subtle laws that govern its operation.
