When a person says, "I could not attain the object of my desire," it means he lacked interest; it was caused by indifference. When one says, "I would like to rise above things, but I cannot," it is because he lacks the power of indifference. Renunciation is the ultimate goal of indifference, and attainment is the result of interest. These two things wrongly used bring wrong result, rightly used bring right result.
