[Advaita-l] Sita Updanishad??

[Chakradhar.N.R nanu]

Hi,
  Is there a updanishad with the name SITA. I was
reading the book "Talks with Bhagvan Ramana Maharshi".
In one of the talks he has quoted a verse from this
updanishad. Learned members in the list please throw
some light on this.

Thanks and Regards,
Chakradhar
