According to Edi S. Ekajati, the existence of the Old Sundanese script had been gradually displaced due to the expansion of the Mataram Sultanate into the Priangan region, except for Cirebon and Banten.

Old Sundanese script is generally found in manuscripts made from palm leaves whose writing is scratched with a knife.

Old Sundanese script is found in columns 89 – 92 in Table van Oud en Nieuw Indische Alphabetten (Holle, 1882).

The Carita Ratu Pakuan manuscript comes from kropak 410 at the National Library of Indonesia (PNRI) which is now in the Sri Baduga Museum Bandung.

We can read Kai Raga's profile from Ratu Pakuan (1970) by Atja and Three Enchantments of Old Sundanese (2009) composed of J. Noorduyn and A. Teeuw.

Through Pleyte's search and interpretation of Ratu Pakuan and the Three Enchantments of Old Sundanese, Kai Raga is thought to have lived in the early 18th century.

And, when Raden Saleh in 1856 searched for ancient relics at the initiative of the Batavian Society of Arts and Sciences (BGKW), Kai Raga's legacy manuscripts were handed over to the painter.

Based on comparisons with other historical relics such as the Carita Parahyangan manuscript and Pustaka Rajya Rajya i Bhumi Nusantara, it can be concluded that the Kawali I Inscription is a sakakala or a memorial monument to commemorate the triumph of King Niskala Wastu Kancana, the Sundanese ruler who reigned in Kawali, the son of King Linggabuana who died.
