Understanding the Eight Thaksa (ทักษา) Positions in Thai Astrology

What is thaksa?

Thaksa (ทักษา) is a frame in Thai astrology that places eight stars (อัฐเคราะห์) in a fixed order and pairs each with an area of life. It is especially well known in Thailand as a tradition used for choosing names. In a paper on thaksa and Thai naming, Amnat Paksasuk of Thammasat University introduces it as a leading guide used for naming monks, royal family members and ordinary people alike.

The word thaksa is explained as coming from the Sanskrit daksha (ทกฺษ), meaning ability or skill. One theory says the name comes from reverence for a sage of that name; another says it suggests the text surpasses earlier astrological works. The classical naming texts circulate under several titles, but all share the same idea of reasoning about a person’s affairs from the influence of eight stars.

The names and meanings of the eight positions

The eight positions come in a fixed order. Here are the Thai names with the meanings traditionally given. Wording differs from source to source, so we have put the widely circulated explanations into plain language.

1. Boriwan (บริวาร): the The People Around Me, such as family, friends and subordinates. Horasat calls it “The People Around Me”.

2. Ayu (อายุ): wellbeing of body and mind, the strength to carry on living. Horasat calls it “Life Force”.

3. Det (เดช): authority, name, standing and the force to move forward. Horasat calls it “influence”.

4. Si (ศรี): fortune, merit, auspicious energy and a comfortable life. Horasat calls it “fortune”.

5. Mula (มูละ): property, home and the ground life stands on. Horasat calls it “foundation”.

6. Utsaha (อุตสาหะ): perseverance and steady effort. Horasat calls it “effort”.

7. Montri (มนตรี): patrons, elders and advisers who help. Horasat calls it “support”.

8. Kalakini (กาลกิณี): obstacles and what is considered inauspicious. Horasat softens this to “what to watch carefully”.

In what order are the eight stars placed?

Thaksa gives numbers to eight of the nine stars, leaving Ketu out: Sun 1, Moon 2, Mars 3, Mercury 4, Jupiter 5, Venus 6, Saturn 7 and Rahu 8. According to the paper above, each number points to people born on the weekday that star guards, and number 8, Rahu, points to Wednesday night.

The order in which stars fill the eight positions is 1, 2, 3, 4, 7, 5, 8, 6. In names, that is Sun, Moon, Mars, Mercury, Saturn, Jupiter, Rahu, Venus. The paper explains that this order corresponds to the eight compass directions, going around clockwise starting from the northeast. Horasat’s calculation uses this order as is. It looks odd at first that 7 (Saturn) comes before 5 (Jupiter), but that is the only rule you need.

Laying it out for your own weekday

The rule is simple. Put the star of your birth weekday in the first position (The People Around Me), and follow the order above to fill the rest. When you reach the end of the order, loop back to the start.

For example, if you were born on Monday, the Moon is your people-around-you star. Then Mars takes life force, Mercury influence, Saturn fortune, Jupiter foundation, Rahu effort and Venus support, and the Sun, having come around again, takes the last position, what to watch carefully.

If you were born on Sunday, the Sun is The People Around Me, the Moon life force, Mars influence, Mercury fortune, Saturn foundation, Jupiter effort, Rahu support and Venus what to watch carefully. The same eight stars sit in different positions for each weekday, and that is the heart of thaksa.

How to read “what to watch carefully”

At first glance the eighth position can feel like a “bad star”. But it is not a curse or a verdict. In the thaksa tradition it was used to avoid the letters belonging to that position when naming, and in everyday life it is enough to take it as a prompt to think about an area where you might handle things with a lighter hand.

Likewise, the star in your “fortune” position does not make you happy. The eight positions are not a scorecard but eight questions. Who is near me now? How are my body and mind? Where does my influence come from? Where does my effort go? Reading them as questions to ask yourself is the most enjoyable use. Leave real-life decisions about health, property or relationships to professionals and your own judgment, not to astrology.

Common misunderstandings about thaksa

The first misunderstanding is “my star is good and my friend’s star is bad”. In thaksa, the same star lands in a different position depending on whose thaksa it is. A star in your “look with care” position may sit in a friend’s “support” position. Stars themselves are not good or bad; the relationship decides the position.

The second is “the eighth position means bad luck”. In the naming tradition the corresponding letters were avoided, but the position is not an alarm bell; it reads more like “an area to handle lightly”. That is why Horasat writes it as “what to watch carefully” and assigns no score or grade.

The third is “knowing thaksa means knowing all of horasat”. Thaksa is one widely used frame in Thai astrology. The actual positions of the stars, the ascendant or Ketu are not part of it. Horasat is a wider world, and thaksa is a small door that suits an entrance.

How to see thaksa on Horasat

Enter your birthday and the eight positions unfold at once, starting from the star of your birth weekday. Each position shows the name and symbolic color of the star that holds it. The short sentences and questions attached to each star are original writing by our editors, not passages copied from traditional texts.

It is even more fun with a friend. We have a screen that shows where a friend’s star lands in your thaksa and, the other way round, where your star lands in theirs. We give no score or compatibility grade, only questions to hand to each other.
