It's possible you're thinking of:
* Sasikala Natarajan: This is a name of an individual, not a Tamil name. It's not a traditional Tamil name and doesn't have a specific meaning in Tamil culture.
* A different name: Perhaps you've misremembered or misheard the name. It would be helpful to know the context or any other information you have about the name to provide a more accurate answer.
Please clarify if you can.
