Frequently Asked Questions
Is Vedic Lagna the same as Western Rising Sign?
No. Vedic Astrology uses the Sidereal Zodiac which accounts for precession of equinoxes (Ayanamsa), making your Vedic Lagna approximately 23-24° earlier than tropical Western astrology.
Why is Lagna called the most important house?
Lagna represents the self (Tanu Bhava). All other planetary energies are filtered through the lens of your Lagna sign and lord.
