Being a Yogi: The Sutras

I have been reading the sutras for a few months now and most of what I am about to post is ...
notes for myself. In essence a flow chart in understanding the Yoga Tenets, themes, process, doctrine or Dogma (?)

Here is a blog on some Central Themes
Summed:

• Ordinary Concisouness and its consequences ( suffering )
• The Goal of Yoga ( Liberation from Ordinary Consciousness)
• Tools and techniques for achieving the goal
• Stages of development
• Obstacles to the Goal
• Yogic Metaphysics
