The Sun mahadasha period comes for 6 years, so the position of the sun in the chart will decide how the sun is going to perform and what kind of effects it will give in these 6 years.
Sun is the main planet in the horoscope, as this is the source of energy, which represents the main source of power in the horoscope, that’s why it represents
1) Father, head of the family, source of income in the family.
2) Government or authority
3) Sun is self-respect. It represents the king & ego.
4) It also represents high temperature, aggression, anger, energy, soul, domination, boss, etc.
So automatically in Sun Dasha these above-mentioned traits/qualities will be seen in the person, whose sun Dasha has been started. The native will become stubborn, and bossy, nature will develop aggression and self-respect can be seen.
Sun always tries to do something in their career, so the native can also try for business where he can become boss, or try for a high authority government job. Because Sun is a king and gets higher name & fame in society. Sun can give the native a higher post or promotion in Sun Dasha where he can fill like a boss.
