"From its inception, Tamil devotion meant that speakers of Tamil had to be at the service of the language, to labor in its name and on its behalf. Glossed in devotional narratives as tamiḻppaṇi, “Tamil work,” or tamiḻttoṇṭu, “Tamil service,” this labor is presented as honorable, virtuous, and meritorious. It is mandatory for all those who claim to be Tamilians for it is an obligation (kaṭamai), even a debt (kaṭaṉ), that they owe, by virtue of being speakers of Tamil, to their language."
