What Asian people contributes singkil to the filipinos during the early period?

The Singkíl originated from the Maranao people who inhabit the shores of Lake Lanao. It is derived from a story in the Darangen, the Maranao interpretation of the ancient Indian epic, the Ramayana. The name of the dance itself means "to entangle the feet with disturbing objects such as vines or anything in your path". It is a popular dance performed during celebrations and other festive entertainment. Originally only women, particularly royalty, danced the Singkíl, which serves as either a conscious or unconscious advertisement to potential suitors.

--well it is not the Indians who really brought it here but I think it is the Indonesians, who already have their own version of the Ramayana before bringing it here.
