To paraphrase part of the article:
The central goal in Taoism is to prepare one for advanced meditation that will allow them to connect with nature, their body mind spirit and soul, and the absolute universal conscious (known as the Tao).
One extremely important part of this process is to smooth out the irregularities inside you, make the mind tranquil, and have it become completely present within the most complex motion patterns possible that can be manifested within both the physical and energetic body's of an individual.
Beyond being an extremely effective martial art and healing practice, Tai Chi is one of the most effective methods for accomplishing the necessary goals outlined for Taoist meditation (another being Ba gua).
Tai Chi was originally developed by adept Taoist meditation masters specifically for that reason, thus is fits quite well within the Taoist disciplines!
