Here's a breakdown of why:
* Lagna: This term originates from Vedic astrology and refers to the zodiac sign rising on the eastern horizon at the time of a person's birth.
* Ascendant: This term is used in Western astrology and represents the same concept as Lagna. It is the zodiac sign that was rising on the eastern horizon at the time of someone's birth.
* Rising sign: This is a more casual term for the ascendant.
Therefore, all three terms essentially refer to the same thing.
