The Sun (Surya) is the Lord of the Day. Its power is absolute from sunrise to sunset.
If you have the Sun in the 1st house (Lagan), your physical and mental energy is directly tied to the solar cycle. Dr. Sharma reveals a highly practical career secret for this placement: You must do your most important work, business deals, and meetings during the daytime ("din ke waqt ka kaam").
If you try to work night shifts, or if you sleep during the day and work late at night, your career will stagnate. To achieve massive progress ("tarakki") and claim your "throne" ("gaddi"), you must align your hustle with the Sun.
