The T or Tau is formed from the number seven, the number that refers to the divine life, the life through the seven–spirit, and Γ (gamma) the symbol of the earth (Gaia). The Tau as a symbol unites thus, the divine and the earthly life.
Remove the upper part from the Ankh symbol and the Tau remains. We may interpret it as the first letter of the typhon, the liberation from evil, from “Satan”.
The Tau cross was also popular among the Druids. The Tau represented to them the symbol of the Druidic Jupiter. Their Tau cross was often formed by a magnificent oak, from which all the branches, except for two very large ones, were cut. From the crown of the oak tree they thus looked like two horizontal arms. The Tau was also used to act as a border sign between different Druidic religious areas.
There is also another explanation of this Tau cross, namely as a phase in the development of humanity. The first phase has no cross, only a pole or phallic symbol. It refers to the development of the abdominal consciousness – to be purely fertile while the consciousness of man was still in the dream state.
Thereafter the stake became a T, a Tau cross, as a sign that the emotional life was now awakening. It stood for the unlimited desire and following this desire, because leadership, authority, is missing. The human being cannot as yet control himself. If you observe the Tau cross you may see the likeness to person without a head. The intersection is the heart, the source of feeling.
The ‘regular’ cross that we know so well does indeed have a “head.” This represents the development of a mental awareness of the individual, which means that he is now able to make choices. The head can curb desire or direct it. The following phase is that of the “cross with roses” where the influence of the ‘rose’ or ‘lotus’ is anchored in the human heart.
