If you feel that someone is working ill against you, close your eyes. Focus on this concept of being attacked, and attempt to give it shape. Consider the force behind it, its form, and the means through which this is to be made manifest in your life.
When you have some grasp of this foulness and have a sense of its distance from you, mentally invoke and call out to the serpent presence you've been feeling throughout this process. Reach out to it and, in turn, connect your essence to this serpentine flow. When you feel that this has been established, reach out and wrap yourself around the harm that's coming your way. Let this sense of presence guide your feelings and thoughts about this trouble, and let its impact decline, recognizing that you only as impacted by it as you allow yourself to be.
Then, feel this serpentine force wrap itself about you as if it were to create a strong cocoon of tightly-wrapped muscle and scales. Feel yourself cool slightly, and let yourself grow comfortable inside this insulated state. Sit in this protected space for a time and feel yourself becoming ensorcelled by this energy, as this act forms of a protective shield of a kind. When you feel that you've done this correctly, open your eyes, ground yourself out, and go about your day. You will likely feel a bit distant from others, but that distance has quite a lot to do with this act of insulating yourself from harm.
This is a tool for inspiring growth as a means of increasing your own strength. This can work beautifully as a means of improving your own throughput and work ethic, and its a means of forcing your spirit/life essence to grow. As you do this, you should feel a sense of calm. If your panic grows, walk away from this and start over. Anxiety will not serve you here, as the act of facing this down reprograms you to an impressive degree.
