One perspective on the four paths of yoga is that they are really one path; knowledge, love, right action, and practice are all necessary for spiritual development. The image of a horse with four legs comes to mind. This seems to be indicated in the Pan Gu password. We do not seperate, we take kindness and benevolence as basis (knowledge), and take frankness and friendliness to heart (love), and speak with reason (right action), and treat with courtesy (right action), and move with emotion (love), and accomplish result (practice). Practicing the Pan Gu Shengong program is a way to align yourself with all the brances of yoga, as well as any other true spiritual tradition. That is also why it can be practiced along with other spiritual disciplines, as the spiritual experience becomes clearer and more manifest in life, it brings knowledge and love, and these combined produce right action, and therefor deepen the practice.
