右手相位（right-handed aspect），包括三分相、四分相與六分相，是指相位向後延伸至行星先前所經過的星座。當相位延伸至行星接下來將前往的星座時，則稱為左手相位（left-handed aspect）。
例如，假設太陽位於獅子座，那麼獅子座的右手三分相位於牡羊座，而左手三分相則位於射手座。獅子座的右手四分相位於金牛座，而左手四分相則位於天蠍座。右手六分相位於雙子座，而左手六分相則位於天秤座。
每顆行星都會發出七道光束（beams）：其中三道朝上或朝北，三道朝下或朝南，另有一道則直接照射至正對面的位置。右手光束向上照射，而左手光束則向下照射。
A right-handed aspect, including the trine, square, or sextile, occurs when an angle extends backwards out to the sign from which a planet would have departed. It is called a left-handed aspect when the aspect is reaching out to the sign to which a planet will travel. For instance, if the sun is in Leo, then the right-handed trine of Leo is Aries, while the left-handed trine is in Sagittarius. The right-handed square of Leo is Taurus, and the left-handed square is in Scorpio. The right-handed sextile would be Gemini, and the left-handed sextile would be Libra. There are seven beams released by each of the planets; three that face upwards or north, three that go downwards or south, and one that shines exactly across to the opposite point. The right-handed beams go up, while the left-handed beams shine down.
