Input: Question: In what century did the era end that saw many faiths and sects spring up in India? Passage:During the Middle Ages of Indian history, many faiths and sects sprang up in religious and social spheres of Hindu society. Their practitioners slowly migrated away from the teachings of the Vedas attaching greater significance to their founders and their preachings. From then onwards polytheism commenced. Great differences developed among the different sects and divided and weakened Hindu society. The caste system based on birth became strong and gave rise to further fragmentation. Like with any aging society without reforms, the customs gave way to superstition and ignorance wherein practice superseded reason and the spread of blind faith threatened degradation of "Hindu" society. The word Hindu is an improper word or misnomer- the correct word is Vedantic or Sanathana Dharma, a religion based upon the Vedas. The word Hindu does not appear any where in the Vedic texts or even the Bhagavad Gita. The word Hindu is a Persian word, used by the Muslims and the renaming of the Vedantic religion to "Hindu" demonstrates the level of weakening to the Vedantic faith. "Hinduism" needs reforms.
