The most important point to remember with transits is that the pattern of the natal chart always determines their value. So, for example if the sun and Jupiter are in a difficult aspect in the natal chart, a positive or easy aspect between transiting Jupiter and the natal sun will not produce the same expected benefit. Also, if planets are not aspected in the natal chart, transiting aspects will in general not have the same effect. In short each person carries the pattern of the natal chart with them all their lives, and the progressed and transiting movements of the planets indicate when the potential in the natal chart will be given opportunities for development.
