The Singnificance of Male and Female signs in Zodiac (Ajit Krishnan)
It is due to the union of purusha and prakriti (or Shiva and Shakti) that creation takes place. Both of these are aspects of the same Brahman. Just as we cannot define light without darkness, or the future without the past, we cannot define one without the other. They are mirror images of one another.
In a regular wall clock, the numbers 1 to 12 increase in the clockwise direction, and the clock hands move in that direction. In a mirror image of this clock, the numbers 1 to 12 would increase in the anti-clockwise direction, and the hands would move in this reverse direction.
The past and future are images of each other (our current karma is a reflection of our past actions). The younger brother (future) is the 3rd house from lagna counting in the zodiacal direction. The older brother (past) is the 3rd house from lagna counting in the anti-zodiacal direction.
Let us replace the numbers 1 to 12 in the clock described above with the zodiacal signs from Aries to Pisces. Matters dealing with male signs would be reckoned in the zodiacal direction, while matters dealing with female signs would be reckoned in the anti-zodiacal direction. Please note that male and female signs are also known as odd and even signs respectively.
We see co-borns and children from the Drekkana and Saptamsa divisional charts. In both cases, we are dealing with physical bodies, and the principle described above applies. Younger co-borns are seen from the 3rd house in D-3. When lagna falls in a male sign, this is reckoned in the zodiacal direction. When it falls in a female sign, it is reckoned in the anti-zodiacal direction. Similarly, the first child is seen from the 5th house in D-7. Once again, the direction depends on the sex of the sign in which lagna falls.
