A thing to remember here is that these posts are strictly meant for the particular planet position. Like, today we are looking at Mercury in Leo, so the description given here may change for you if your Mercury is although in the sign of Leo but with conjunction with or aspected by other planets.
So, lets see what Mercury can do in Leo without any conjunction or aspect from any other planet. 1st lets see what these 2 things represent --
Mercury represents communication skills, marketing, calculative ability, younger siblings, hobbies, skills with hands, intelligence, quick decision making, logical thinking, youthfulness etc.
Leo is 5th sign of zodiac belt, hence it represents the things associated with 5th house of horoscope like Love, Creativity, Arts, Being on Stage etc. Besides that, Leo is basically the Lion. This is the sign of feeling like King or Queen. Also, it is a sign of independence, Confidence, Ego, Self Esteem etc. Leo is consisted of 2 and half Nakshatra namely Magha, Purva-Phalguni and Uttara-Phalguni. Leo's lord is Sun.
So, now Mercury comes into the sign of Leo. As Leo is the sign of taking the Center-Stage and feeling like King of world, these people love to rule the world through their communications. It means they can be in any of the fields like Art, Theater, Cinema, Politics, Preaching etc. Any job in which person is required to express themselves through communications and impact the public mind is good for them. Here the qualities of Mercury are brightened by the light of Leo's lord Sun. Actually, these people can't remain without public attention. Apart from these, they can be excellent spokesperson for Celebrities and Political Parties.
Now, the impact of Mercury will depend on Mercury's position in a particular Nakshatra. If Mercury is in Magha Nakshatra, then Ketu's position will decide the functioning of Mercury in Leo as Magha's lord is Ketu. If Mercury is in Purva-Phalguni Nakshatra, then its lord Venus will be deciding factor. If Mercury is in Uttara-Phalguni Nakshatra, then Sun's position will be deciding Mercury's impact.
Also, as Sun is Lord of Leo, Sun's condition will have the highest say on Mercury's impact in Leo.
Tomorrow, Mercury in Virgo.
