I am Shiva-this is the great meditation of the yogis in the Himalayas ... Heaven and hell are within us, and all the gods are within us. This is the great realization of the Upanishads of India in the ninth century B.C. All the gods, all the heavens, all the worlds, are within us. They are magnified dreams, and dreams are manifestations in image form of the energies of the body in conflict with each other.
