''What is the meaning of "you must take the right attitude"?''
The right attitude is the attitude of trust, the attitude of obedience, the attitude of consecration. <ref>http://incarnateword.in/cwm/07/2-february-1955#p1,p2</ref>
A sort of witness attitude, in which the inner consciousness looks at all that happens as a spectator or observer, observing things but taking no active interest or pleasure in them. <ref>http://incarnateword.in/cwsa/30/inner-detachment-and-the-witness-attitude#p16</ref>
