who composed the original story of mahabharata in oral form
Mahabharata Traditionally, the authorship of the Mahābhārata is attributed to Vyāsa. There have been many attempts to unravel its historical growth and compositional layers. The oldest preserved parts of the text are thought to be not much older than around 400 BCE, though the origins of the epic probably fall between the 8th and 9th centuries BCE.[2] The text probably reached its final form by the early Gupta period (c. 4th century CE).[3] The title may be translated as "the great tale of the Bhārata dynasty". According to the Mahābhārata itself, the tale is extended from a shorter version of 24,000 verses called simply Bhārata.[4]
Bhagavad Gita Bhagavad Gita comprises 18 chapters (section 25 to 42)[33][web 2] in the Bhishma Parva of the epic Mahabharata and consists of 700 verses.[34] Because of differences in recensions, the verses of the Gita may be numbered in the full text of the Mahabharata as chapters 6.25–42 or as chapters 6.23–40.[web 3] According to the recension of the Gita commented on by Adi Shankara, a prominent philosopher of the Vedanta school, the number of verses is 700, but there is evidence to show that old manuscripts had 745 verses.[35] The verses themselves, composed with similes and metaphors, are poetic in nature. The verses mostly employ the range and style of the Sanskrit Anustubh metre (chhandas), and in a few expressive verses the Tristubh metre is used.[36]
