Ribhu Gita

  "Everything is only a concoction of time, space and energy. All else is the trite talk of people who dislike the effort of sadhana which takes them to the Self. This talk is based on their dense ignorance of the Self. Only by persistent practice and experience of sadhana (practice), can one arrive at the truth that all concepts of souls, world, and the cause thereof are just evanescent shadows on the screen of Siva-Self-Brahman."
