It is the birth anniversary of Shrimad Bhagavad Gita, the book that appeared from the mouth of Shri Krishna. In this book, along with success, the sources of happiness and peace have been told. During the Mahabharata war, on the Ekadashi of the Shukla Paksha of the month of Agahan, Shri Krishna preached the Gita to Arjuna. Mokshada Ekadashi fast is also observed on this date.
Shri Krishna only preached the Gita to Arjuna, but along with Arjuna, Sanjay also heard this sermon. Sanjaya had narrated this knowledge to Dhritarashtra. The context of the Gita is a part of the Mahabharata. Ved Vyas ji had spoken Mahabharata and Ganesh ji had written it.
Ved Vyas had given divine vision to Sanjay
Sanjaya was a favorite servant of Dhritarashtra. When the Mahabharata war was about to begin, Veda Vyasa wanted to give Dhritarashtra a divine vision so that he could see the battle, but Dhritarashtra refused. After this Vyas ji gave divine vision to Sanjan on the behest of Dhritarashtra.
Staying in the palace, with the help of clairvoyance, Sanjaya had narrated to Dhritarashtra what he had witnessed about the war. Sanjay told Dhritarashtra every incident happening in the war.
This is the context of Gita sermon
The Mahabharata war was about to begin. The armies of the Kaurava and Pandava sides were standing face to face. At that time Arjuna asked Shri Krishna to take the chariot between the two armies. Shri Krishna obeyed Arjuna and took the chariot between the two armies. From there, Arjun abandoned the idea of fighting after seeing Bhishma Pitamah, Dronacharya, Kripacharya and other family members on the Kaurava side.
Arjun told Shri Krishna that I do not want to fight this war.
Having said this, Arjuna put down his bow and arrows.
Shri Krishna understood that Arjuna is entangled in delusion and doubt. After this the Lord preached the Gita to Arjuna. Sanjay also heard this sermon and narrated it to Dhritarashtra.
