Acharya Prashant explains that the human mind is fundamentally troubled by change because it perceives itself in relation to external circumstances and relationships. When these circumstances change, it feels as though a part of one's own self has been severed, leading to deep suffering. He asserts that the deepest human desire is to find something unchanging and eternal upon which absolute faith can be placed. This inherent resistance to change indicates that the mind cannot find peace in anything temporary or transient.
