Acharya Prashant explains that the word OM has no inherent significance because any word is merely a sound produced by the human mind. He states that when a sound is heard, the mind attaches a meaning or image to it, which is a manmade process that cannot lead to silence or peace. He argues that if OM is treated as a word with associated religious or spiritual meanings, it only serves to further activate and agitate the mind with thoughts and images. Acharya Prashant clarifies that these sounds were originally intended as a technology to silence the mind by not attaching any meaning to them. He emphasizes that as long as OM remains a religious symbol or an external input that triggers thoughts, it is meaningless and useless. To move into silence, one must move away from the world of thoughts and images, challenging the listener to discover what OM can be beyond a mere sound or word.
