A thing to remember here is that these posts are strictly meant for the particular planet position. Like, today we are looking at Sun in Leo, so the description given here may change for you if your Sun is although in the sign of Leo but with conjunction with or aspected by other planets.

So, lets see what Sun can do in the sign of Leo. 1st lets see what these 2 things represent -

Sun represents Personality, King, Government, Father, Authority, Career, Top Positions, Ego, Self Esteem, Health, Education 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 when Sun comes into Leo then it is in its own sign, so obviously it will feel extremely powerful. So these people are extremely confident about themselves and independent. As confidence level is so high, these people find it difficult to take orders from others. Hence, it is always advisable for them to do their own work. Even if they are in jobs, they can progress only when they are given independent charge of their work and their is none to interfere with their work. As Sun is in its own sign, all the qualities of Leo like Creativity and Arts get perfect environment. Only thing which can be their doom is when they become Egoist or someone who is over-confident. Actually, they want people to praise them or treat them like a celebrity, so that their ego may be satisfied every moment and they continue to feel like King or Queen. As Sun represents Father, all these qualities can be seen in Father too. Father would also have similar characteristics and working independently.

Now, the condition of Ego, Confidence or Self Esteem will be within limits or not will depend on Sun's position in a particular Nakshatra. If Sun is in Magha Nakshatra, then Ketu's position will decide the functioning of Sun in Leo as Magha's lord is Ketu. If Sun is in Purva-Phalguni Nakshatra, then its lord Venus will be deciding factor. If Sun is in Uttara-Phalguni Nakshatra, then it will be best because its lord is Sun itself, so Sun will be in its own sign and in its own nakshatra, protecting and nourishing the qualities of the sign.
