Madam Mrs. Swagata Om,
Your idea to learn astrology is highly welcome. I do not know other systems as I follow KP astrology only. To learn from me is not possible. I advise you to purchase KP readers written and brought out by Prof. Sri. K.S.Krishnamurthi jee and go thoroughly. As you are an educated and have interest to learn, you can easily understand well.
In the KP readers – 2nd reader “Fundamental Principles of KP astrology” is quite useful. 6th reader is “Horary Astrology” which is useful for predictions of queries related to 12 bhavas. 1st reader – How to cast a horoscope is a guide to cast the horoscope. Today everyone depends on computer software like KP Starone (exclusively KP) or other. So you start with 2nd reader.
One should know the difference of a sign and a bhava. All the signs are in an imaginary belt in which all the planets are situated. Bhavas or houses are the imaginary divisions those surrounds the earth. They are based on the the principle that day and night are not equal. Signs are used to know the strength of the planets as planets pass from one to another in the signs only.
Bhavas are taken for the matters we need to study. The rays of the planets pass from the signs through the imaginary bhavas and reach the native and influence by their cosmic energies. The receiving end i.e the native is also composed of by cells with certain configuration of planets at birth which is called the birth chart. The birth chart is like ROM in a computer. The external magnetic forces act on the basic configuration and the native experiences the changes. This is the principle of astrology. This is given for your understanding of basic information. Rest you secure with your efforts.
Good Luck
JVS Rao (KP follower)
