II. One of the names of this thread is Yajna-Sutra. Yajna means

Brahma, or the Supreme Spirit, and Sutra the thread, or tie. Collectively, the compound word signifies that which ties a man to his spirit or god. It consists of three yarns twisted into one thread, and three of such threads formed and knotted into a circle. Every Theosophist knows what a circle signifies and it need not be repeated here. He will easily understand the rest and the relation they have to mystic initiation. The yarns signify the great principle of "three in one, and one in three," thus:--The first trinity consists of Atma which comprises the three attributes of Manas, Buddhi, and Ahankara (the mind, the intelligence, and the egotism). The Manas again, has the three qualities of Satva, Raja, and Tama (goodness, foulness, and darkness). Buddhi has the three attributes of Pratyaksha, Upamiti and Anumiti (perception, analogy, and inference). Ahankara also has three attributes, viz., Jnata, Jneya, and Jnan (the knower, the known, and the knowledge).
