In judo, you are trained to take advantage of your opponents' momentum to throw them off balance, and to the ground. You don't have to be bigger or stronger to win a combat.
There's a spiritual judo arena for each of us. When we start to try to shun evils, learn truths, and do good, we're entering the arena. We're going to engage in contests, combats.
We can expect that our opponent (our old, selfish mind/self, which believes false things and loves evil things) will try to use our new momentum to throw us off balance, and down. If we shun an evil successfully, once or twice, it will pull us into the evil of self-congratulation. If we learn some exciting new truths, it will yank us further into a pride in our own intelligence. If we fail a few times, it will throw us into despair or lead us to abandon the whole project.
If we know to expect these judo tactics, can we do better at keeping our balance? Yes, for sure. We can recognize that we're in the spiritual arena, in spiritual combats, or temptations. We can try to keep our balance, keeping the Word as our touchstone, and getting advice and support from people we love and trust. We can move without over-reaching, learning truths to match with new-found loves for doing good things. We can practice, over and over again, and not lose heart.
Judo is not mentioned in the Bible, but when you look, you can see the techniques at work:
Three times in the Old Testament, there are stories of good high priests - Aaron, Eli, and Samuel - who have evil sons that they don't rein in. Initially strong, good efforts get pulled off balance, either by inattention or pride or neglected practice. (See Leviticus 10:1-2, 1 Samuel 2:12-34, and 1 Samuel 8:1-3)
The three most prominent kings of Israel, Saul, David, and Solomon, all start well, but get seduced by their power, pride, or wealth, which seem to corrupt them.
In another case, during the Exodus, Moses has led the Children of Israel out of Egypt, and towards the land of Canaan. He's doing well, obeying the Lord's commands. But at Meribah, he gets impatient, and loses trust in the Lord, and tries to take matters into his own hands. As a result, he's not permitted to enter the Promised Land. (See Numbers 20:6-13)
In Swedenborg's work, "The New Jerusalem and its Heavenly Doctrine", there's a chapter about temptation that begins in section 196. In section 197 we find this statement:
"Temptation is a combat between the internal or spiritual man, and the external or natural man (See Arcana Coelestia 2183, 4256)"
When you set out to make spiritual progress, you're entering the judo arena. Your new-forming spiritual self will combat your habitual "natural" self. You'll be fighting to keep your balance, and -- if you stay aware that you're in a spiritual battle, you'll even be able to see ways to throw evil and falsity off-balance, to the ground.
