The Vedas are the most ancient sacred texts of Hinduism. Each of the four Vedas consists of the metrical Mantra or Samhita’ part and the prose ‘Brahmana’ part giving discussions and directions for the detail of the ceremonies at which the Mantras were to be used and explanations of the legends connected with the Mantras and rituals. Both these portions are termed shruti (which tradition says to have been heard but not composed or written down by men). The Rigveda (Sanskrit: ऋग्वेद ṛgveda, from ṛc “praise, shine” and veda “knowledge”) is an ancient Indian collection of Vedic Sanskrit hymns. It is one of the four canonical sacred texts (śruti) of Hinduism known as the Vedas.The text is a collection of 1,028 hymns and 10,600 verses, organized into ten books (Mandalas). A good deal of the language is still obscure and many hymns as a consequence seem unintelligible. The hymns are dedicated to Rigvedic deities. For each deity series the hymns progress from longer to shorter ones; and the number of hymns per book increases.
