Being a man or woman "of the Tao" means being attuned to cycles of change; being consciously aware of our place within the web of Life; and acting in the world according to the principles of wu wei – naturalness, ease and spontaneity.
Taoist Cosmology
In terms of Taoist cosmology, Tao is the realm that is the source of "the 10,000 things," i.e. all of manifestation, though itself is transcendent of any particular "thing." To have experiential access to the Tao, in a stable and continuous way - a feat achieved in large part through the practice of Inner Alchemy - is to be an Immortal, a Buddha, an Awakened One.
Tao In Relation to Other Spiritual Traditions
What "Tao" points to is similar to what "Buddha" or "Buddha-nature," or "Dharmakaya," or "Primordial Wisdom" points to in Buddhism; what "God" points to in (contemplative forms of) Christianity; what "Self" or "Pure Awareness" points to in Advaita Vedanta; what "Brahman" points to in Hinduism; and what "Allah" points to in Islam and Sufism.
Universal Path of the Tao
All Spiritual and Religious Paths seek
The natural flow of the universe--
The Tao, which literally means the Way,
Is the way of nature and universe.
The Tao is the path of our natural reality
About the world, our spiritual path & ourselves.
It is the real practice of body, mind & spirit;
Not just a philosophy of the mind.
When you have the true sense of it's meaning,
It's true knowledge and wisdom,
You will be able to make
The correct decisions in your life.
The Tao is not a religion or science
Requiring no initiations or ceremonies;
And its truth goes beyond
Any one single path or view.
The Tao is the outcome of all religions
Leaving them behind as seasons change,
Yet it transcends all religion & science
But still contains their essence.
