Tula (Libra) is masculine, movable and airy. These qualities show the method of its operation. Tula (Libra) does not depend upon other influences to be effective. Wherever and however it operates, it will create an impact. That is its positive or masculine quality. It can never remain stationary: it will always impart a thirst for greater and greater achievement. Whatever one's level of prosperity, Tula (Libra) will always induce the ego to thirst for more. Outwardly, however, it does not create much of a show, for a great deal of its operation is psychological, for which reason it is said to be airy. Shukra (Venus) owns the sign, signifying that the sign is operating primarily in the realm of materiality. The Surya's (Sun) debilitation and Shani's (Saturn) exaltation in this sign have connections with this trait.
The 7th sign of the zodiac is full of deeper implications, and an understanding of its mysteries might unveil many clues to the finer forces m Nature as well as those hidden dimensions of human beings which can be employed either for useful or nefarious objectives. Many of the meanings of this sign are suggested indirectly by such attributes as Tauli (weigher), Vanika (merchant), Yuka (the link), and Tula (balance).
