The Bhagavad-Gītā is the most important text in the smrti (what is remembered) literature of India, as distinct from the śruti (what is heard) literature which is traditionally regarded as ultimately authoritative. The Bhagavad-Gītā has been assigned a date ranging from the fifth century B.C. to the second century B.C. The Indian religious tradition places the Gītā at the end of the third age of the present cycle of the universe and the beginning of the fourth, namely the Kali Yuga to which we belong.
