Taoism is an ancient Chinese philosophy that is becoming popular in the West for its emphasis on simplicity, naturalness, and harmony. It is sometimes classified as a religion, but unlike most religions, modern philosophical Taoism does not require any specific form of initiation.

[edit] Steps

Take some quiet time for yourself and read the Tao Te Ching, an ancient book of Chinese folk wisdom attributed to the sixth-century BC sage Lao-Tzu.
Research Taoism further. Many translations of Taoist texts can be found in bookstores, libraries, and the Internet. See external links.
Call yourself a Taoist if you find Taoist ideas appealing. To be consistent, begin applying the philosophical principles to your actions.
It would be wise to join a Taoist group if one is available to you. Joining a Guan can benefit you greatly and improve the pace in which you achieve peace of mind and body.
Use the ideas of the Tao to restructure your thinking and the way in which you live your life. This may lead to spiritual and philosophical communion. This communion is also known as "peace." Even before peace is achieved, it will begin to spread outward into other people and the world around you.
Learn an internal cultivation artform such as Qi Gong, Tai Chi,or Taoist Yoga.

[edit] Tips

Be sure to find a quality translation of Tao Te Ching and other Chinese texts. Since the English and Chinese languages are so different, a good translation can make all the difference.
Wu Wei (non-action, or non-ado) is a fundamental principle of Taoism, and is a good place to start. Wu Wei is the concept of knowing when to act and when not to act. This allows one to accomplish all that is necessary, without using too much energy. Other important principles include the "Three Jewels of the Tao": Compassion, Moderation, and Humility.
Another important Taoist teacher was Chuang Tzu (Zhuangzi). His writings offer a more down-to-earth and humorous perspective on the principles of Taoism. Together, Lao-Tzu and Chuang Tzu make up the yin and yang of primary Taoist texts. Reading both is recommended.
Some people refer to Taoism as "Daoism." This spelling is phonetically more accurate, although its use is not as widespread. Either variation is acceptable, so use whichever you prefer. No matter how you spell the word, it is pronounced "dow-izm."
Tao (or Dao) means "The Way." However, this definition should be taken as a beginner's meaning, since many people argue that the true Tao cannot be put into words. Lao Tzu writes, "The tao that can be told is not the eternal tao."
Chinese "neijia" (internal martial arts) follows many Taoist principles. Accordingly, some call them "physical Taoism."
Read "The Tao of Pooh" and afterwards, "The Te of Piglet" for some easily accessible insight on Taoism. Other good books to introduce one to Taoism are the cartoon books "The Tao Speaks" and "Zhuangzhi Speaks" by Tsai Chih Chung.
Ever been "in the zone?" This could be a modern description of "being one with the way" - effortless action by non-action. If that makes sense at all, you've got a good start.

[edit] Warnings

Do not try to follow the way to impress others or to appear 'deep' for you will not receive a reward for doing so, you will not benefit from Taoism if you approach it with this attitude.
