Basic Tenets of Taoism Taoism, like any other belief system, has certain guiding principles that make it what it is. Tao The Jing the Chinese symbol for Tao is a combination of two separate symbols: one representing a human head, and one representing the act of walking. Rather, he will seek to become closer with the universal nature of everything and everybody. Seeing Clearly A Taoist will seek to see everything as it truly is, without embellishment or falsehoods. Piercing through the veil of illusions that we call life is but one of many activities that a follower of the Tao participates in. Knowing Yourself To understand who and what you are is a special quest of the Taoist. This speaks to the Seeing Clearly principle, in that you need to know yourself in order to func- tion in the most natural fashion possible. It is not their place to do so, nor does it advance their own spiritual quest. They remain apart from material things, rec- ognizing their needs and distinguishing them from their wants. Thinking Independently Taoists are known for being independent thinkers, not followers of the crowd. I often use the term Wolf or Sheep—do you move and think with the common crowd, or do you stand apart? They place no limits on com- passion or love, but engage fully in understanding and spiritually recognizing all other beliefs. Faith In Life It is all too easy to become pessimistic, the more we experience the bad parts of life. They do not fear change, understanding that it is a natural function of living, and welcome the opportunity to experience and learn new things every day. Right Here, Right Now Taoists are not paralyzed by a fear of the unknown of the future, nor are they caught looking backward longingly into the past. They realize that right here, right now is all we have to work with, so we should make it the best present moment that we can. They know that our time here is short and that going through life mad and sad at everything is a waste of life. They joyously participate in the suffering, as well as the happiness of life. In fact, it helps us deal with adversity and allows us a greater world view. The greatest goal of a Taoist may very well be to become one with Nature, to feel the rhythms, ebbs, and flows of life in an intuitive fashion. Nonresistance Taoism advocates seeking the path of least resistance in life. This is intimately re- lated to the act of nonstriving and being a natural person. Using Taoism in Everyday Life So how does all of this philosophy apply to you, dear reader? In practicing Taoism, you become a better person, both for yourself and for your loved ones. You shed the petty grievances and character flaws and learn to be more compassionate, loving, caring, and gener- ally fun to be around. For the past 2,000 years, traditional Western thinking has been dominated by a dualistic, either-or approach: either something is good, or it is bad; desirable or undesirable; someone is an ally or an enemy. We perceive experiences to be either positive or negative and we expend much energy in trying to eradicate that which we consider to be negative. From a Taoist point of view, this is like trying to erase the negative current from electricity because it is not positive. Taking these differences for the way things really are leads to arguing, fighting, and even killing—all because of this and that. We dislike parts of ourselves and struggle to change, not trusting that our own inner nature will of its own accord move towards a harmoni- ous balance. Indeed, we be- come an agent of change ourselves, rather than resisting it while desperately cling- ing to one experience or perception or the other. Bad luck becomes good luck and crisis contains the opportunity for growth. We can choose to cooperate with this complement of opposites by not denying, suppressing, or struggling against unwanted discomfort or pain, but rather by accepting all facets of our existence, good and bad, as the natural flow of the Tao. By following the path of acceptance and responsiveness to change we can be- come, in the words of the Taoist philosopher Chuang Tzu, true women and men of Tao. This unceasing flow of change manifests itself as a natural order governed by unalterable, yet perceivable laws. Strangely enough, it is the constancy of these governing principles (like the rising and setting of the sun and moon and the changing of the seasons) that allows people to recognize and utilize them in their own process of transformation. From the Taoist viewpoint this represents the ultimate stage of human existence. The writings of the legendary Taoist sages Lao Tzu and Chuang Tzu furnish us with specific principles as a guide to attaining this state of oneness. At the same time, it is not to be considered inertia, laziness, or mere passivity. Rather, it is the experience of going with the grain or swimming with the current. Our contemporary expression going with the flow is a direct expression of this fundamental Taoist principle, which, in its most basic form, refers to behavior occurring in response to the flow of the Tao. Among these is the need to consciously experience ourselves as part of the unity of life that is the Tao. Lao Tzu writes that we must be quiet and watchful, learning to listen to both our own inner voices and to the voices of our environment in a noninterfering, receptive manner. In this way we also learn to rely on more than just our intellect and logical mind to gather and assess information. All of this allows us to re- spond readily to the needs of the environment, which of course includes ourselves. And just as the Tao functions in this manner to promote harmony and balance, our own actions, performed in the spirit of wu-wei, produce the same result.
