The Bhagavad Gita is a 700-verse Hindu scripture that is part of the ancient Indian epic, the Mahabharata. The text is a conversation between Lord Krishna and Prince Arjuna that takes place on the battlefield of Kurukshetra just before the start of a great war.

In the Bhagavad Gita, Krishna offers guidance and advice to Arjuna, who is struggling with doubt and indecision about whether to fight in the upcoming battle. Krishna teaches Arjuna about the nature of reality, the importance of performing one’s duty (dharma), and the path to spiritual liberation. It offers a synthesis of different ideas and approaches to the attainment of ultimate reality and presents the path of devotion (bhakti yoga), action (karma yoga), and knowledge (jnana yoga) as complementary paths to the ultimate goal of life. 

One of the key themes of the Bhagavad Gita is the idea that all actions should be performed as a sacrifice to God, without attachment to the fruits of those actions. Krishna teaches that detachment from the material world and devotion to God are the keys to liberation from the cycle of birth and death (samsara). The Bhagavad Gita continues to be widely read and studied, and is considered a classic of Indian literature and spirituality. The Bhagavad Gita is considered to be one of the most important Hindu texts and is widely regarded as a concise guide to Hindu philosophy and spirituality.
