Acharya Prashant explains that the pure self, or Brahman, is the incorruptible center of the mind that remains unaltered and uninfluenced by external conditions. While the ordinary mind is fickle and constantly affected by factors like time, wealth, or physical environment, the pure mind is that to which nothing makes a difference. He clarifies that 'difference' is synonymous with change, time, and influence. When there is no urge to expand, shrink, or know, one is in the state of Brahman. This state of completeness and inactivity belongs exclusively to the truth. He warns against the danger of the false mind mimicking the characteristics of the truth. While the truth does not need to know anything or go anywhere, the false mind must actively seek knowledge and the right environments to dissolve its own falseness. If a person's falseness becomes indifferent to change and nothing makes a difference to it, that falseness has become chronic and deeply entrenched. For the false to be uprooted, it must remain susceptible to influence and change, unlike the truth which is inherently beyond all differences.
