This is just an image from a video game … but, it grants you access to a very interesting field of energy if you meditate on it and study the context from which it was pulled.
The meditation is simple: conjure all the “demons” you feel are attached to you, then use the blade to eradicate them. If the demons are particularly persistent, stab them in the heart, break the sword at the hilt, and leave it there. They will remain permanently inactive.
The photo will just help move things along if meditated on with eyes open and focused on a single point until it becomes blurry, takes 2-4 minutes usually, for me. You are charging the concept yourself, but the field already exists. We collectively created it.
If you ever do find yourself needing to break the sword at the hilt, or just want to supercharge the Eternal Crucible Blade to wield it in ways you feel it can be used, I found this image from the scene to work best:
