The 12th Pathinen Siddhar Peedaathipathi is the successor to the 11th Pathinen Siddhar Peedaathipathi. This 11th Pathinen Siddhar Peedaathipathi was the Father of the Later Chola Empire (785 CE to 1279 CE). His Holiness was also the Arasa Guru (Raja Guru) of all the kings including the RajaRaja Chola I.
The entire world never get to know about these Pathinen Siddhar Peedaathipathis because they had to be the force behind all the social and political changes taking place in the world. Because they work intensely behind the screen for the good of the entire mankind, they do not spend their time to publicize themselves. It becomes the responsibility of the disciples of these Pathinen Siddhar Peedaathipathis. Due to the heavy burden of numerous tasks assigned to the disciples, they fail in the task of publicizing about their Gurudevar.
