The concept of rta may be understood as follows:
That which is ordained by rta fills the whole world, but the particular manifestations of rta are in those processes of nature which always remain constant and arouse the idea of regular recurrence. Rta has the following meanings:
CW6 ¶ 348Established order
Regulation
Destiny
Sacred custom
Statute
Divine law
Right
Truth
Ordinance
(Right) way
Direction
Course (to be followed)
The concept of rta is a libido symbol like sun, wind, etc. Only rta is less concretistic and contains the abstract element of fixed direction and regularity, the idea of a predetermined, ordered path or process
CW6 ¶ 355Rta is, therefore, a kind of philosophical libido symbol that can be directly compared to the Stoic concept of heimarmene. For the Stoics heimarmene had the significance of creative, primal heat, and at the same time it was a predetermined, regular process (hence its other meaning: “compulsion of the stars”)
