The Yogis, the celibates, the austere penitents, and all sorts of clever people have failed.
In an instant, He changes the beggar into a king, and the king into a beggar. He fills what is empty, and empties what is full. Such are His ways. He Himself spread out the expanse of His Maya, and He Himself beholds it. He assumes so many forms, and plays so many games, and yet He remains distinct and detached from it all. Incalculable, infinite, incomprehensible and immaculate, He has misled the whole world.
So give up all your doubts; prays Nanak, O mortal, focus your consciousness on His Feet.
Siri Guru Granth Sahib (537)
