This unionist system of worship is supported by a monastic melting pot of Vadama people of the Thiruvananthapuram district of Kerala and Kanyakumari district of Tamil Nadu, along with descendants of Nambudiris, Iyengars, Iyers, Madhwas, and other Indo-Aryan people who migrated to the region in different waves to support pilgrimage in the region.

This region also known as Ay Kingdom was spread to the borders of Central Travancore in ancient times.

Vadamas are believed to be the migrants from the north of Vindhya reaching the other coast of Tambapanni in the south crossing Pamba after Agastya and Pulastya.

All these Hindu sub-groups have ancestors who co-existed peacefully with Buddhists and Jains and share Pali, Sanskrit, Malayali, Tamil, southern Pandyan and even ancient Yogic traditions and heritage with their neighbours.

The ancient ports in this region connected the people to Sri Lanka and Maldives as international trade brought migrants from many parts of India and other kingdoms in this geographic triangle which had a common economic and melting pot cultural history until the British rule began.
