Acharya Prashant explains that every emotion is fundamentally rooted in a thought, and without thought, an emotion cannot arise. He notes that people often overvalue emotions, sentiments, and tears, mistakenly believing they represent some deep divinity or truth. However, he points out that all thoughts are influenced by external factors and are not truly one's own. By logical extension, since thoughts come from the outside and emotions arise from thoughts, emotions themselves are external influences rather than personal attributes.
