We are passing through the midst of many traps, so it is not permissible to proceed neglectfully if we want to avoid the snares. Let us keep our eyes wide open, imitating the many-eyed Cherubim, so that we may deride the clumsy tricks of Satan and ascend with the wings of divine thoughts through the spiritual ether. Thus we may offer the health of our souls as a fragrant incense to God, Who dwells in the heavens. Just as the health of children brings joy to their parents, likewise our good Father-God- rejoices to see our souls healthy.
