A birth chart or a natal chart is something that most people with knowledge in Vedic Astrology reads, and it has different level of inquiry. In Vedic Astrology, you see what the naked eye can see but the meaning and the core value of what you see is hidden and transcribed by someone that has knowledge of what the meanings and the signs are.
Reading a natal chart would be like that of a lens of a camera, in a wide-angle lens. An Astrologer is able to read your life and defines your true destiny according to his or her reading, your potentials and what you can do to change your course or if you want to stay on the course.
Some people are not able to understand this and they are sometimes lacking a portion of their spiritual connection with their own signs and houses. That’s why it is evitable to understand the true indication of a person’s psychology, character and life potential.
Because the Sun, Moon, planets, and primary angles in the sky are constantly in motion relative to the earth, as each second passes the natal chart/astrological chart is changing (albeit slowly) and a new chart is created for every moment at each location. A natal chart is extremely personal and unique, depending on the specific date, exact time, and precise location of the birth.
In natal chart, we see the exact time of an individual’s birth at a particular place on Earth, just for the purpose of gaining information about the individual. Solar chart however is a natal chart that is erected when the date of birth is known but not the time of day. A lot of natal charts are being introduced here and around the world since time can define what the true natal chart means for us and for other people.
