The archaeological sites along the Indus have revealed many terra-cotta figures resembling gods and goddesses in the Vedic literature, some of which are still worshipped.
Though religious figurines abound, temples inexplicably are absent from the Indus cities. Because the Indus valley script is yet to be deciphered, much of the Dravidian culture and religion remains a mystery.
Buddhism was an offshoot of Hinduism, with Gautama Buddha, seeking the truth of life, deciding to launch his own religion. Hinduism is the only major religion lacking an adequate explanation as to its origin. Similarly, Sikh religion founded by Guru Nanak draws most of its ideals, thoughts and beliefs from Hindu scriptures, though it has now a distinct existence of its own, with different mode of worship and the Holy Guuru Granth Sahib as the guru.
