Vedic cosmology is a tapestry of complex esoteric principles which explains the inner workings of the soul, human mind, universe and the elemental relationships of various realities which can be experienced while taking birth on planet earth.
For some Gods are only idols but their true meaning is the very relationship of the inner psyche, elements and the cosmos. The original word for Hinduism is Sanatana Dharma and this translates to Universal Truth.
Hinduism uses various symbols and idols in order to unlock the mysteries of life and the sacred relationship between the human kind and the vast universe.
