In aikido we have many techniques in which we lock uke's wrist. However, simply locking out the wrist is not enough: we must also apply the technique to uke's lower body, so that uke's knee is knocked away. Thus we are able to see that the technique has had a real effect. For example, in nikajo, if we just lock the wrist and uke has sufficient strength, the technique will not be effective. If, however, we send our energy through the wrist in order to destabilize the knee, even if uke resists we will be able to unbalance him. It is perhaps possible to say that an aikido technique is where we are able to unbalance the other person even without hurting him.
In most cases, when we try to apply a technique, we concentrate only on the place where we think the control will have its effect, and often we try to apply our strength against the angle where uke’s power to resist is strongest, so that there is a clash of power. But however strong uke is, there is always one line that is weak. By redirecting the power into that line and thus turning all of uke's power back on himself, he will not be able to keep his feet (stay on balance).
In order to find that line, we must work to improve our overall sensitivity to, for example, how uke looks, his posture, balance, and so forth. In order to achieve that, it is necessary to experience many different sorts of power on our own body.

CONTROLLING UKE’S KNEE
控制受方的膝蓋
圖1~4 當受方抓住我們的道服時，改變他的力量到他最弱的地方，如此我們可以使他的膝蓋失去平衡。
提供你的力量到最弱的點
在合氣道裡有許多技法可以鎖住受方的手腕，然而，只是簡單的鎖住手腕是不夠的：我們仍舊必須施技至受方的下盤，使受方的膝蓋被撞擊，於是我們就可以看到那個技法的真實效果。例如，在二教中，假如我們只是鎖住手腕，而受方還擁有足夠的力量，技法將會是無效的。然而，假如我們傳導我們的力量穿過手腕造成膝蓋的不穩定，即使受方反抗了，我們還是能夠使他失去平衡。可以說合氣道的技法就是即使在不傷害對方的情況下，也可以讓他失去平衡。
在大多數的情況中，當我們嘗試做技法時，我們希望得到成效，所以只專注在我們想控制的點，所以我們常將力量放在受方反抗力量最強的地方，也因此產生不協調的力量。然而再強壯的受方，也是會有一條虛弱的線。藉由引導他的力量到那條線上及使他的力量回到他身上，他將無法站立（保持平衡）。
為了找到那條線，我們必須加強我們全身的敏感性，例如，受方看起來如何？他的姿勢、平衡等等。為了達到這個目的，讓我們的身體感受不同來源的力量是必需的。
