Peng is the most well known of Tai Chi's 8 Primary Energies, and curiously it may be the one energy people have the most difficulty with. That may be because of how rare it is to discuss how to actually create the Quality of Peng. Once you have learned to establish Yin and Yang Quality, Peng goes beyond that black and white duality, and creates a stable energy structure made of both Yin and Yang Quality. And while formless, it does function like a structure, creating a tangible sense of support and transmitting this profound sense of floating to those you are in contact with.
This skill is based off of the Yin and Yang Qualities built by the Yin and Yang Qigong. Here's a link to that practice:
