For exemple the ready made sticks for Sur that is avaible from Shechen Gompa are not to be used for Sang. This is why they distribute also special sticks for Riwo sang cho. Be careful with all these things, and take correct instructions from a competent Lama .
But three "whites" already contain animal fat. The tibetan yogurt which is an ingredient in both Sur and Riwo Sangcho conatin animal fat. If animal fat isn't allowed in Riwo Sangcho, then why does the text list three whites as ingredient?
The difference of Shechen Gompa Sur and Riwo Sangcho incense stick is that the sur one contains 3 whites and 3 sweets while the Riwo sangcho one don't contain 3 white and 3 sweets. I even feel that their Surpo incense sticks are more suitable for Riwo Sangcho practice.
