Quotes:T
H. P. Blavatsky
T. T — The twentieth letter of the alphabet. In the Latin Alphabet its value was 160, and, with a dash over it (T) signified 160,000. It is the last letter of the Hebrew alphabet, the Tau whose equivalents are T, TH, and numerical value 400. Its symbols are as a tau, a cross +, the foundation framework of construction; and as a teth (T), the ninth letter, a snake and the basket of the Eleusinian mysteries.
