Mercury ast (Budh Ast / Mercury Combust) in vedic astrology
In Vedic astrology, Mercury ast (Combust Mercury) occurs when Mercury comes very close to the Sun in the zodiac. Due to the Sun’s intense brightness and heat, Mercury loses its visible strength and becomes combust (Astangata or Moudhya). Since Mercury stays close to the Sun, combustion is a frequent phenomenon for this planet.
Mercury represents intelligence, communication, speech, logic, business, mathematics, analysis and decision-making. When Mercury becomes combust, its intellectual and communicative qualities may weaken or become internally expressed.
