I have always kind of liked the way Andrew D. Chumbley put it in his article "What is Traditional Craft".

"The Traditional Craft is the Nameless Way of the Arte Magical. It is the Path of Wytcha, the heart's calling of avocation to Cunning Man and Wise Woman; it is the Hidden Circle of Initiates constituting the living body of the Elder Faith. Its ritual is the Sabbat of Dream-made-Flesh. Its mystery lies in the Land, below the feet of Those who tread the crooked track of Elphame. Its scripture is the way of wort-cunning and Beast-charming, the treasury of lore re-membered by Those who revere the Spirits; it is the gramarye of ear-whispered knowledge, beloved of Those who hold sacred the secrets of the dead and entrusted to They who look ever onward... If any ask about the Traditional Craft, their answers lie in its native land: the Circle of the Arte of Artes!"
