Acharya Prashant explains that the practice of reciting the name of the Lord, known as Japa, is necessary because human beings are inherently restless and talkative. He observes that people are constantly engaged in internal or external dialogues, driven by an insecure ego that seeks validation and self-assertion. This constant mental activity means that the mind is always occupied with various names and forms. Since the mind is stubbornly addicted to thinking and talking, it is impossible for most to jump directly into silence.
