In this video, Dr. K K Aggarwal, President Heart Care Foundation of India and Group Editor in Chief MEDtalks, will explain the chanting of Aum, AM, Amen, Amin, Khong scientifically, in this video. He explains that whenever we have physical pain, the body produces a sound which is a vowel A, E, I, O, U. He further says that there are studies available which shows that whenever we chant a vowel, body produces interleukin-2 which is 200 times stronger painkiller than aspirin. Also, when we weep, our body produces a sound which is known as nasal consonant which he explained by Dr. Aggarwal. Hence, in pain when we chant these seed mantras with a vowel and nasal consonant, these are physical and spiritual healers.
