Should you falter on your path, stop for a moment and catch your breath. Breathe in deeply if you can. This slows the brain, giving it oxygen, and pulls vital Life Force energy through the rest of the physical vessel. Oxygen is far more important than you think. Just as your blood carries nutrients to the cells, oxygen carries an energy you cannot see, but an energy that enlivens the spirit nonetheless.
Take in a breath and relax, knowing that upon this very breath rides consciousness. Oxygenate the body. Exercise is most beneficial for this task, preventing not just physical stagnation, but spiritual as well, for the very reasons stated above.
Yes, you may stumble. Deep breaths will bring you back to a state of peace. You can pick yourself up and dust yourself off if you fall to the side of your path. Stand there and breathe deeply for a few moments, and in that very act of breathing you will once again find your way.
