Preguntas frecuentes

Signs and houses are the two main wheels of the birth chart, but they answer different questions. The <strong>sign</strong> describes <em>how</em> an energy expresses itself — its style, its element, its temperature — while the <strong>house</strong> indicates <em>where</em> it manifests, that is, in which concrete area of your life. For example, Mars in Aries speaks of impulsive action; Mars in the seventh house brings that action to the realm of partnerships. Both are needed to read a planet precisely.
