Sooner or later, everyone dies. When they do, their physical abilities, intellectual attainments, social status, and so on, all cease to exist. Only the Inner Self, to the extent that it has been developed, survives beyond the death of the body. One of the great regrets people face at the end of life is the opportunities they chose to miss. No one regrets the quiet work, effort, and struggle devoted to inner growth. People regret the things that took them away from it.

If a person could really understand what the Tao-Teh-King [道德经] is about he would give up everything else.

-Abdullah Dougan in The Call of Silence

From Patrick Kelly's book Relax Deep Mind:

Taiji is an internal style of Chinese martial art, stressing the principles of relaxation and yielding both in application and in daily life. Taijiquan training develops inner strength and harmony through the coordination and relaxation of Mind and body. Externally, Taiji is the art of movement for health and self defence. Internally, Taiji is Raja Yoga, the science of Mind and internal energy or Qi (气)...Daoism provides the philosophy while Taiji provides a practical method for incorporating those Daoist principles into practice.

People of all ages and degrees of health are equally able to practise Taiji. It leads people from the mundane everyday state to a position of inner knowledge, inner calmness and inner power. Success in practice requires an attitude of genuine enquiry, patience and perseverance, an openness to practise according to the teaching and a willingness to constantly examine and refine your motives according to your inner conscience...To experience the full potential benefits, once begun, Taiji should be thought of as a lifetime practice.

Today, Taiji is well established around the world. A variety of teachers and schools allows students to find the methods – whether presented as an art of movement, a fighting skill or more deeply as a spiritual path – which best suit their life’s direction. In these times, the outer school teachings have spread widely throughout China and also throughout the Western world. In almost every park in China they can be found. The true inner school teachings however – almost never to be found in public parks – are much more difficult to meet.
