As we will note when we reach Confucius and The Analects,
poetry has enormous influence in Chinese culture: particularly, a body of work
known as The Classic of Chinese Poetry.
The Bhagavad-Gita is a very small part of the immense Hindu
epic the Mahabharata.
(Basically an epic about a war of succession between two inter-related royal
families in India.)
A little background: Plato is a student of Socrates – one of
the main speakers here. In all of the dialogues Plato wrote, he uses Socrates
as his main speaker.
