Acharya Prashant explains that silence is not a specific practice but is the essence of all spiritual practice. He describes the mind as inherently talkative and prone to meaningless chatter, which manifests as useless actions in life. Silence, or Maun Sadhana, involves understanding that the mind's chatter requires a participant. If one refuses to engage or respond to the mind's thoughts and impulses, the chatter cannot sustain itself. He advises that instead of participating in the mind's gossip, one should focus on their own work, which should be driven by love or a sense of urgency.
