Well . . . nearly every Tibetan school teaches some form of shine, and doing simple shine with an object as he's describing doesn't normally require any special transmission, although some good instruction is always helpful. Since this stuff came from Tenzin Wangyal, who is a very competent teacher and whose teachings on this and a lot of other subjects are available in books, in recordings and online, it would be reasonable to seek out additional instruction on shine by him, or even write Ligmincha if there is a specific question. But with shine, doing a lot of it frequently renders many questions moot, as things sort of fall into place after a while.
Shiné is a fairly universal practice and the instructions shouldn't differ too much at all lineage to lineage. The goal is calm-abiding, as was mentioned. Shiné with support, without support and then released shiné which is essentially the natural state. Shiné is the first of the four naljors of dzogchen sem sde. In shiné the aspirant identifies stillness and familiarization with that aspect is the foundation for the other three naljors.
