In Western astrology, Mercury  is the ruling planet of Gemini and Virgo. According to Manilius, it is an inconstant, vivacious, and curious planet that presides over the right leg. Called "the winged messenger" in Alan Leo's What is a Horoscope?, Mercury represents the principles of mentality, thinking patterns, rationality, transport, reasoning and communication. This follows from the planet being named after the Roman messenger god Mercury.

Mercury rules over Wednesday. Dante Alighieri associated Mercury with the liberal art of dialectic.

In Chinese astrology, Mercury is ruled by the element water. In Indian astrology, it is called Budh, a word related to Budhi ("intelligence").

The word is Budha.

I don't know if it's Budha or Budhi,this is how I've found it in the respective article.

Yes it is Budha in India, not Budhi.

So from the meaning of this word,the person whom was called Budha was inspired,interesting thing.
