Dr. Rishi Rohit Sharma provides a beautiful, cost-free daily routine for anyone with the Sun (Surya) in the 1st house (Lagan).
To maximize the royal, authoritative energy of the Sun, you don't need expensive gemstones. First, while taking your daily bath, simply chant the name of Lord Vishnu ("Narayan Narayan"). This purifies the aura.
Second, follow the rule of royal charity. Out of whatever you earn, dedicate a small, fixed percentage (like 25%) to helping others ("chawanni upkaar mein lagaye"). This consistent act of giving will exponentially increase your fame, respect, and divine aura ("tej yash maan") every single day.
