The Treasury (Tian Fu, 天府) in the Self palace (Ming Gong, 命宫)
The Self palace is about who you are at core. Keeps and protects. Wealth that is stored rather than started.
Which star is in your own Self palace?
Only your own chart can say. It needs your birth date, hour and place: about a minute, free, and nothing you type is stored.
What the classic says, Zi Wei Dou Shu Quan Shu (紫微斗数全书), volume two
The command (令) star, and a keeper of wealth. In the seat of the self with the Power transformation (化权) or the Fortune transformation (化禄), welcome; with the two Patrons, the Scholar and the Artist and the two Aides (魁钺昌曲左右) in accord, a rise into high company.
天府土，南斗化令星，为财帛主。天府入男命吉凶诀：天府之星守命宫，加之权禄喜相逢，魁昌左右来相会，附凤攀龙上九重。天府入限吉凶诀：限临天府能司禄，士庶逢之多发福，添财进喜永无灾，且也润身也润屋。
The classic also has lines on a woman’s chart, reading a life by its sex; they are left out here, in the Chinese as well as the English. The source link has the full text.
“Well placed” and “badly placed” refer to the star’s brightness in the branch the palace falls on: the same star in the same palace reads differently bright and dim, and the clause says how.
How this placement actually turns up
- Well placed (exalted or strong) in 68% of those charts, badly placed (fallen) in 0%, in between the rest.
- Alone in the palace in 50%; sharing it with The Emperor (紫微) 18%, The Iron (武曲) 17%, The Mystic (廉贞) 15%.
- How often the conditions the classic’s line names actually occur — one of the six helper stars (左辅右弼文昌文曲天魁天钺) with it: 40%; Lu Cun (禄存) with it: 8%.
Counted by casting every day from 1950 to 2009 at each of the twelve hours — 262,980 charts, 8.3% of which have The Treasury here (every main star sits in every palace in about one chart in twelve). A count, not a reading.
Never read alone
Zi Wei reads a palace together with the one opposite it and the two in trine. For the Self palace those are Travel (迁移) opposite, and Wealth (财帛) and Career (官禄) in trine. Whatever stars sit there change what The Treasury means here — which is why a page like this one can only give the classic’s line, and your own chart has to give the rest.
If a transformation lands on it
- Fortune (化禄): eases it and finds gain inside it — the star still does what it does, but smoothly and to some profit
- Power (化权): intensifies it and puts you in charge of it — more of the star, and more of it under your hand
- Merit (化科): makes it visible and gives it a name — the star's workings become something you are known for
- Trouble (化忌): sharpens it and makes it cost — the star's difficulty is where the chart puts its weight
What each transformation does to a star is this site’s reading, not a line from the classic.
Which star is in your own Self palace?
That needs your birth hour and place. The hour is corrected to true solar time, using the clock your birthplace actually kept that year.
