It is very difficult, but we can overcome the difficulty by constant practice. We must learn that nothing can happen to us, unless we make ourselves susceptible to it. I have just said, no disease can come to me until the body is ready; it does not depend alone on the germs, but upon a certain predisposition which is already in the body. We get only that for which we are fitted. Let us give up our pride and understand this, that never is misery undeserved. There never has been a blow undeserved: there never has been an evil for which I did not pave the way with my own hands.
We ought to know that. Analyse yourselves and you will find that every blow you have received, came to you because you prepared yourselves for it. You did half, and the external world did the other half: that is how the blow came. That will sober us down. At the same time, from this very analysis will come a note of hope, and the note of hope is: “I have no control of the external world, but that which is in me and nearer unto me, my own world, is in my control. If the two together are required to make a failure, if the two together are necessary to give me a blow, I will not contribute the one which is in my keeping; and how then can the blow come? If I get real control of myself, the blow will never come.” (II, 7 -8)
Swamiji gives the advice as to how to overcome the obstacles that appear on our way as we practise detachment. It is only through constant practice that one can accumulate spiritual power. Such a power is necessary to face the beatings that nature inflicts on us. Vedanta puts before us the example of the tortoise (withdrawing its limbs inside) and of a steady flame of a lamp in a windless atmosphere.
