Hi @direwolf -
I've trained under a few different lineages, such as Moy Yat and Chu Shong Tin. But I was appointed as a Sifu under Sifu Greg Choi, whom was also a direct student of Grand Master Yip Man. Every school has slight differences as well as cross-overs, but predominantly what I discuss on Steemit is specifically from what I learnt from Sifu Greg.

And yes, the Sui Nim Tao is a form of Qi Gong Meditation. The body movements can be used as a focal point for the mind, which assists in emptying out thoughts. Just a small note...your focus should not be on completing the move, as that is a future state. The focus should be on the present state, such as 'moving'.

And finally, there are many points that can be derived from mediation. Clearing the mind, or emptiness meditation is just a single aspect. After all, I haven't yet disclosed any of the Internal Qi Gong components of the Sui Nim Tao yet, but I will. With these teachings, you will clear the mind, strengthen the immune system, increase your vitality, become more flexible, and build a repertoire of skills in the 'energy arts' to name only a few of the potentials.

Best of luck and keep practicing.
