How is Mercury read? The classical rules

  • Mercury exalted Gives its good results in full: intellect, speech and skill (BPHS ch. 3 sl. 59-60).
  • Mercury in its moolatrikona Gives three quarters of its good results (ch. 3 sl. 59-60).
  • Mercury in its own sign Gives half of its good results (ch. 3 sl. 59-60).
  • Mercury in a friend's sign Gives a quarter of its good results (ch. 3 sl. 59-60).
  • Mercury debilitated or in an enemy's sign Its good results are nil (ch. 3 sl. 59-60).
  • Mercury in deep exaltation, with the 9th lord in the 9th Abundant fortune after the 36th year (BPHS ch. 20 sl. 27-28).
  • Mercury in the Lagna, with a benefic 4th lord aspected by benefics Honour from relatives (ch. 15 sl. 5).

One rule never decides a chart on its own: the classical method weighs the planet, the houses it owns and occupies, the planets with and aspecting it, and the running dasha together.
