TILANG, FIFTH MEHL, FIRST HOUSE:
ONE UNIVERSAL CREATOR GOD. BY THE GRACE OF THE TRUE GURU:
The Lord infused His Light into the dust, and created the world, the universe. The sky, the earth, the trees, and the water - all are the Creation of the Lord. || 1 || O human being, whatever you can see with your eyes, shall perish. The world eats dead carcasses, living by neglect and greed. || Pause || Like a goblin, or a beast, they kill and eat the forbidden carcasses of meat. So control your urges, or else you will be seized by the Lord, and thrown into the tortures of hell. || 2 || Your benefactors, presents, companions, courts, lands and homes - when Azraa-eel, the Messenger of Death seizes you, what good will these be to you then? || 3 || The Pure Lord God knows your condition. O Nanak, recite your prayer to the holy people. || 4 || 1 ||
Jhatka concept is only to satisfy your tastes of your tongue...
