Charvaka, also known as Lokayata, is a philosophical school that originated in ancient India. It is known for its materialistic and skeptical views, rejecting the existence of a higher power or supernatural entities. As such, Charvaka does not have any specific text or scripture associated with it.

Unlike other philosophical schools in India, Charvaka did not have a formal written tradition. Instead, its teachings were passed down through oral tradition and were primarily expressed in the form of aphorisms and verses. These were often attributed to the founder of Charvaka, Brihaspati, who is believed to have lived in the 6th century BCE. However, there is no concrete evidence to support this claim.

The lack of a written text or scripture in Charvaka can be attributed to its emphasis on empirical evidence and rejection of traditional authority. The Charvaka philosophers believed that knowledge should be based on direct perception and experience, rather than blindly accepting the teachings of scriptures or religious authorities. This rejection of traditional texts and authority is reflected in one of their famous aphorisms, "The Vedas are the work of fools, knaves and demons."

Despite the absence of a written text, Charvaka's teachings were widely spread and influenced other philosophical schools in ancient India. Some of its key ideas can be found in the works of other philosophers, such as the Buddhist philosopher Nagarjuna and the Jain philosopher Kundakunda.

In modern times, some scholars have attempted to reconstruct the teachings of Charvaka based on the fragments of verses and aphorisms that have been preserved in other texts. However, due to the lack of a comprehensive written text, there is no consensus on the exact beliefs and principles of Charvaka.

In conclusion, while Charvaka is a significant philosophical school in ancient India, it does not have a specific text or scripture associated with it. Its teachings were primarily transmitted through oral tradition and can be found in fragments in other texts. The absence of a written text is reflective of Charvaka's emphasis on empirical evidence and rejection of traditional authority.
