Svarga, also known as Indraloka and Svargaloka, is the celestial abode of the devas in Hinduism. Svarga is one of the seven higher lokas in Hindu cosmology. Svarga is often translated as heaven, though it is regarded to be dissimilar to the concept of the Abrahamic Heaven.

Loka is a concept in Hinduism and other Indian religions, that may be translated as a planet, the universe, a plane, or a realm of existence. In some philosophies, it may also be interpreted as a mental state that one can experience. A primary concept in several Indian religions is the idea that different lokas are home to various divine beings, and one takes birth in such realms based on their karma.
