That's why I was saying that Vedic mantras are not joke. Words are arranged in such a way that it produces special effects in whole physiology. For example, there is no literal meaning for Vedic mantras like Hreem Shreem Kleem but when pronounced in a cyclic rhythmic pattern, it produces trance effects on brain and mind. The whole mind becomes rejuvenated. The enormous latent powers within one's brain can be activated by chanting special Vedic mantras. It's a pure science that ancient Rishis worked on and gave us valuable mantras for peace and prosperity. It is true that the whole universe is merely a vibration!
