In considering what is possible, negate all the constructions of this particular world. Imagine existence with no restraints, even those of space, time, and causation. In doing so, you'll find that what is possible is truly boundless and that we human beings are capable of imagining this fact, even if this said imagining is quite limited.
Philosophical consciousness—that means of inquiring into all levels of being and phenomena—takes precedence in those individuals who dare to apply a critical lens to all thoughtforms that relay our own collective and personal understandings. Without philosophical consciousness, we would be deprived of the tools necessary to scry all realms for truth, and we would therefore remain blind to it. This faculty of humanity, gifted by nature, enables all of us to find those diamonds of truth in the rough of deceit and illusion and, through its power, take us back to who and what we really are.
