Acting as a Guardian
Just Being There
by Madisyn Taylor

To act as a guardian to somebody during a difficult time is a most beautiful gift of support.

One of the greatest gifts we can give another human being is to act as their guardian. Whether this gift is related to a specific situation or is representative of an ongoing commitment, we each benefit from the association. To protect someone is to walk with them in challenging times and see them through safely to the other side. In doing this, we grow with them. And those under our guardianship derive confidence from our support and assistance, enabling them to persevere through almost any conditions. 

There are many reasons we feel inspired to serve as guardians to those we care for. Sometimes just holding the space for somebody allows them to do what is necessary to grow or heal. We may simply want to see that our friend or loved one is taken care of and equipped to prevail over difficult circumstances. We may also sense that we are in possession of knowledge our loved ones are lacking yet need in their current stage of development. Our offer to serve as a guardian may also be both unsolicited and unrelated to any one situation. Instead of helping someone we care about cope with a specific challenge, we may find ourselves providing them with a more general form of emotional sustenance that prepares and strengthens them for challenges yet to come. 

Our ability to empathize with those under our guardianship is our greatest asset because our comprehension of their needs allows us to determine how we can best serve them. Even when this comprehension is limited, however, the loving intentions with which we enter into our role as guardian ensure that our care and protection help others grow as individuals while living their lives with grace.
