Acharya Prashant explains that living in the present means living in that which truly exists and ceasing to live in illusions. He defines presence as that which is, and absence as that which is not. To live in the present, one must stop living in self-imagined worlds and narratives. He emphasizes that facts serve as the door to the truth; while facts themselves are not the truth, they are essential enablers that help an individual break away from illusions. He suggests that because the ego can easily manipulate words, one should prioritize research, analysis, and numbers in their spiritual process, as mathematics is a more difficult tool for the ego to misuse.
