Sadhu Sundar Singh

In India, an ox with blindfolded eyes goes round an oil-press all the day long. When his eyes are unbandaged in the evening he finds that he has been going round and round in a circle and that although he has succeeded in producing some oil he has gone no further. Although the philosophers have been at it for hundreds of years, they have not reached their goal. Now and then, after much labour they have produced a little oil, which they have left behind them, but it is not sufficient to meet the sore need of mankind.
