Many interactions (transits) occur between the moon and various planets as it cycles around the earth every month. Each aspect typically lasts only a few hours, and there are typically 13 void periods each month, which can last from a few minutes to hours, sometimes as long as several days.
The moons transit through each sign sets the stage to affect our feelings. The moon is connected with our emotional life which changes daily. As the moon aspects various planets, this too can affect our moods and feelings, playing a role in the outcome of events that occur in our lives.
As the moon enters its void of course phase, it is as though it is taking a rest. For a short time we may feel out of sorts and it is considered best not to make major decisions or purchases during a void of course phase. Sometimes, we may not even notice this period it is so subtle, but decisions made during this period will often not turn out as expected. During these periods it is best to focus on spiritual matters or reflect, rather than act, if possible.
