When building the Serpent's Spine in this way, you're creating a series of connective points between yourself and the target of your choosing. If you have access to physical goods representing your end goal, you can utilize the creation of the Serpent's Spine to empower the link itself and draw you nearer to your goal by extension.
Case in point, a common wealth spell involves the use of dirt from four banks, either mixed in oil with the appropriate herbs or used fresh with the correct additional ingredients. For the sake of discussion, we'll be using the oil-creation methodology. This is not a particularly complicated rite, but its powerful, and that alone renders it appropriate to discuss within this context.
With this in mind, you've got your dirt from four banks, chamomile (wealth cultivation), mugwort (energy movement), and cinquefoil (grabbing what blessings are presented to you) all mixed into an oil and appropriately consecrated. Now that this has been done, you're about to start working your magic & that's where building the Serpent's Shrine comes into place.
Hold the bottle containing the oil in your hands and focus upon this physical vessel. Feel it within your grasp and have some sense of what's within, as this connection will be built by this process. From there, begin to chant a mantra or enn of your choosing and feel the words wrap themselves about this bottle, empowering the oil and bringing it to life.
*For spells like this, I'd suggest using a mantra/enn for Dzambhala, Tara, or Bune. They're all wealth-creation entities, so it comes down to what you're looking to work with.*
Here, I'll use the White Dzambhala practice, as it resonates with me & its mantra has a strong beneficial juju to it. So with this oil in hand and the mantra "Om Padma Krodha Arya Jambhala Hridaya Hum Phat" in mind, begin to chant these recitations over and over again, feeling the words slip into and around the jar, filling it up and making the oil itself feel whole bodied and powerful. Continue this practice until you feel that oil humming with energy - if you don't feel it, you're not done.
When you've reached that point where the energy is palpable, makes you tingle, and really *sings* to you, that's when you can go about constructing the ritual. Anoint a single candle, cover it in oil, and while being mindful of fire risks, place around it small clumps of basil (adds energy and vigor), rosemary (creates a sense of surface tension), and a touch of rue (adds force to the spell) if you're feeling adventurous.
Then, spark a light and pull the trigger on the spellwork. Feel your words and breaths fine-tuning the spell and connecting it to your being. Congratulations, you've now done some serious rootwork with simple tools and mental focus.
You'll likely feel pretty exhausted after this, and often folks report feeling light-headed and a little giggly. Eat some chocolate and ground, then go about your day. Don't leave the flame unattended for long, and be sure to check in on it regularly. Watch how the candle burns, as the wax formations that run off can be indicative of any successes or lacks on your part. ;)
