Along the same lines, many Western writers have added their testimony to the Yogi principle of the manifestation of thought into action. Kay has written: "A clear and accurate idea of what we wish to do, and how it is to be effected, is of the utmost value and importance in all the affairs of life. A man's conduct naturally shapes itself according to the ideas in his mind, and nothing contributes more to success in life than having a high ideal and keeping it constantly in view. Where such is the case one can hardly fail in attaining it. Numerous unexpected circumstances will be found to conspire to bring it about, and even what seemed at first to be hostile may be converted into means for its furtherance; while by having it constantly before the mind he will be ever ready to take advantage of any favoring circumstances that may present themselves." Along the same lines, Foster has written these remarkable words: "It is wonderful how even the casualties of life seem to bow to a spirit that will not bow to them, and yield to subserve a design which they may, in their first apparent tendency, threaten to frustrate. When a firm, decisive spirit is recognized, it is curious to see how the space clears around a man and leaves him room and freedom." Simpson has said: "A passionate desire and an unwearied will can perform impossibilities, or what seem to be such to the cold and feeble." And Maudsley gives to aspiring youth a great truth, when he says: "Thus it is that aspirations are often prophecies, the harbingers of what a man shall be in a condition to perform." And we may conclude the paragraph by quoting Lytton: "Dream, O youth, dream manfully and nobly, and thy dreams shall be prophets."
