The first is to move towards; so to intend is to acquire an inwardness, perhaps even an unfamiliar inwardness, which asks me to go away from the many mechanical or automatic concerns of outward things, which provoke an endless series of reactions, towards an inner concern that forms itself around my sense of myself as a Being.
This brings me to the second meaning of to tend, which is to attend to: to value, to honor, to see.
I can have a wish; and the wish can attract the forces that help me to have an intention. But to have a real intention is a gift.
Now, this may seem a difficult concept to agree with, since we presume almost to a fault that what is or is not good is determined by us, by our thought; yet real Grace teaches that goodness comes before mankind and even before Being itself, as we know it. Another way of saying it would be that Being is goodness.
Now, law means that which is laid down and fixed; and because we see physical and chemical principles established in this way, we think first, through our sciences, that the universe is immutable. We then think, through the vehicles of our societies and institutions, that principles of morality and rightness are fixed things, even though the evolution of society's understandings over time conclusively proves that this is never the case. (Take the examples of slavery, and of gay marriage rights, for example.)
So we interpret goodness always from a fixed and relative point, and believe we understand something about it, whereas the absolute truth is that we can only understand goodness through the heart of God.
Our failure to understand this inwardly, through prayer and contemplation, is why the world is such a mess. Any human being who truly searches inwardly will discover their own inner thickets are filled with exactly the same thorny brambles as the outside world: we are all tangled in them.
