Description:

However, it sounds like it could be used in a poem or story; maybe to describe a secret note, since its a bit like the word for "letter" in some languages.

This names avatar is a big deal, a super important part of Vishnu. People really respect this avatar. Lakshmi, the wealth goddess, is closely related—shes often seen as the wife of this names main form. Big festivals like Diwali (the festival of lights, celebrating good winning) and Janmashtami (this avatars birthday) are all about this name.

You might see a slightly different spelling, like "Chittee," but its rare. So, there arent really any established variations.
