Not at all. You just have to blend like crazy to get it to incorporate and smooth out. This is also known as "beating the crap out of it". However, it might hurt your arm if you don't use a stick blender.
I did some googling to see if I could find pictures which showed good examples of ricing. I came across this Soap Queen article on Soap Behaving Badly
which you might find helpful.
Also, if you don't mind, I'd like to separate your question about ricing and our replies to it and make into a new topic for the Beginner's section. It might be informative for other people.
