Acharya Prashant explains that fear is a symptom indicating that the mind is clinging to something transient and impermanent. Fear arises from the thought of loss, which at its core is the fear of annihilation or death. When an individual identifies themselves with external objects, possessions, or even subtle concepts like reputation and status, they live in constant anxiety because these things are subject to time and decay. The speaker emphasizes that fear cannot exist without a wrong association or identification. He clarifies that one does not need to discard useful objects, but rather remove the attachment to them. Clinging to things does not make them more secure; instead, it makes the individual feel more insecure.
