Probably the Shangpa Kagyu version of shi-nay/shamata. If I remember correctly it is a series of forms & colors representing earth, wind, fire & water, etc.
Do you want to invest a lot of your time and effort in doing shi-nay? It isn't easy. But if that is what you wanted to do anyway then it is an excellent practice and you should make the effort to go. But if you're only doing Dharma tourism, maybe it's not worth the effort to simply get some karmic seeds.
A human being has his limits. And thus, in every conceivable way, with every possible means, he tries to make the teaching enter into his own limits. ChNN
