Negative thought patterns deplete life energy, which is different from physical energy. Have you ever noticed how food does not replenish or revitalize life energy? Life energy requires a different kind of sustenance that is not physical in form. This sustenance is non-tangible and can only be accessed when we free ourselves from energy blocks.
To free yourself, mindfully embrace the bigger picture in life and be open to seeing what you cannot see. For every negative thought pattern, there is also a positive. This is the wisdom of yin yang where opposing energies are present in everything. Dissolve negative energies by staying open to the myriad of possibilities that exists in any given moment!
