The first three shabads were uttered by Guru Nanak and the fourth by Guru Ram Das and fifth by Guru Arjan Dev. It is the most harmonious Naad ever uttered. It multiplies the aura to the sensitivity of protection that it eliminates any negativity for miles and miles. When you are endangered by any species of direct or indirect source; when you want to protect yourself with the surrounding of the entire magnetic field of the earth, recite Kirtan Sohila. It is a cure for Insomnia! The religious and artistic value of these hymns is superb.
