Western astrology considers specific angles between planets as aspects. They are major and minor. The popular thinking is that some aspects are harmonioius and the others are not. But in my view the aspects are positive and negative and the result depends on the positions of planets in houses.
I have evolved a techique named 'Algebra of Aspects' based on the sidereal zodiac and the western aspects. It consists of two parts. In the first part, I have taken charts where Moon signifies the X house. In the second part, I have dealt with the charts where the luminary does not signify the X. I have assigned polarity to Moon, the aspect and the key planet. The result is got by multiplying the polarities.
