We want to control things as much as possible so that we can better predict the results of actions. This is a legacy from our childhood where understanding of the relationships between causes and results were necessary for our survival both inside and outside the family.
Once we understood those relationships we would do our best to ensure that we were pressing the right buttons to obtain what we wanted or to avoid what we didn't want. This has evolved for some into the mantra of whomever has control has the power.
If we were to think about someone who is passionate about something; in most cases we will think about someone who wants us to join them in what ever they are passionate about. There is little or no attempt to control they just drag you along.
In looking at control and passion in this light they are really opposites. The more we are controlling people and events the less passion comes through.
If we are looking for more passion in our lives then perhaps we need to let go of controlling and let our passion speak for us instead.
