Hinduism

Hinduism is one of the oldest religious traditions still practiced in the world today and deeply associated with astrology. Indo-European immigrants to the Indian subcontinent, called the Vedic peoples, constructed an Indian religion embodied within the Vedas (sacred Indian/Hindu texts). Minimally, the term has been used to designate those non-Buddhist, non-Jaina, non-Muslim, and non-Sikh forms of religious life in the Indian sub-continent which have in some (often rather loose) sense drawn inspiration from these groups of texts: the Vedas (prescriptions of a variety of types of ritual practice) and associated work on ritual theory; the books about social duty and political obligation of Manu and other works that pertain to the concept of dharma "duty"; the two epic stories, the Mahabharata, of which the Bhagavadgıta – Karna’s advice to Arjuna on the eve of battle – is a part, and the Ramayana, the story of Rama; and the Upanisads ("hidden teachings" about the self) and the commentaries on them.

The Vedic peoples
The Vedic peoples were brought into Northern India from the north by the Aryan invaders after 1200 BC.
