The planets behind 31
Thai phone numerology reads a two-digit sum like a pair of planets: the tens digit leads and the units digit follows. Sum 31 is therefore Mars leading Sun.
| Digit | Planet | Meaning | Bright side | Shadow side |
|---|---|---|---|---|
| 1 | Sun | honour, leadership, confidence | decisive, trusted | pride, stubbornness, working alone |
| 3 | Mars | drive, courage, action | hard-working, brave, gets things done | temper, clashes, accidents |
Root digit 4. Adding the digits until one is left, 3 + 1 = 4, is the international numerology method many people use alongside. 4 is the energy of communication, structure and trade that runs on talk.
