Koorcham

[P.S.NARASIMHAN]

For what are all religeous /rituals a koorcham is to be used. Is it to be used only by Purohits or even by gruhasthas? What for a koorcham is used?

[SR Sankaran]

Namaskaram. May I request to indicate how to make koorcham and pavithrams - here I wish to know these articles used during Tharpanams.
