The First Quadrant, containing the First, Second and Third Houses of the Zodiac, falls in the northern and eastern hemispheres of the chart and is bound on either side by the Ascendant and the I.C. The First House focuses attention on the self, the Second on possessions and Third on communication and self-expression. Therefore, a convergence of planets within this quadrant would concentrate an individual's focus on personal growth, identity and self-enrichment.
The next three houses, the Fourth, Fifth and Sixth comprise the Second Quadrant, falling in the northern and western hemispheres. The Fourth House emphasizes the extension beyond self into concern for loved ones, especially family and home. The Fifth House deals with pleasure, with love affairs and creative expression and children, while the Sixth House relates to our forays into occupations and interactions with coworkers. Therefore, a convergence of planets within this quadrant would concentrate an individual's focus on an outward development, the moving out from oneself to integrate with the world through family, romantic and career relationships. As we enter the Third Quadrant, containing the Seventh, Eighth and Ninth Houses, we move farther away from the individual's concerns and closer to the higher realms of being, to the more abstract human goals.
Falling in the southern and western hemispheres, and beginning at the Descendent, the Seventh House deals with our partnerships and interpersonal contracts, things like marriages and business agreements. The Eighth House is occupied by the concepts of transformation, rebirth and sexuality, of the occult and of death, while the Ninth describes our relationship to higher learning, philosophy and travel. Therefore, a convergence of planets within this quadrant would concentrate an individual's focus on the way their actions and beliefs impact the world as well as their most intimate relationships.
The Fourth Quadrant, comprised of the Tenth, Eleventh and Twelfth Houses, pulls us back around to our innermost selves. The Tenth House trades in social status and in our dealings with authority, and the Eleventh in our social obligations and group associations. The Twelfth House is where our dreams and secrets lurk, as it's the House of the Subconscious. It butts itself right up against the First Quadrant and our First House sense of ourselves. Therefore, a convergence of planets within this quadrant would make for an individual who channels much energy into their relationship with a larger social group, an individual who finds their satisfaction in their public status. Also, some emotions may be suppressed if planets lie in the Twelfth House. 相关知识：
