To Gangothri: 16

The most confidential of all the secrets was abridged and granted by Siva. That which is spoken as Self is non-self only; the mind (which speaks thus) is non-self also. The world too is non-self. Be certain that there is no non-self. -- Sri Siva Rahasyam
Be of the certitude of the absence of non-self by rendering naught all forms of thought, by forsaking all forms and by the conviction that Brahman alone is. -- Sri Siva Rahasyam
By the non-cognition of the mind, there is nothing to be thought of; by the non-cognition of the body aging is not. With the knowledge that Brahman alone is, be of the certitude that there is no non-self.-- Sri Siva Rahasyam
By the non-thinking of feet there is no motion and by that of hands action there is none. With the knowledge that Brahman alone is, be of the certitude that there is no non-self.-- Sri Siva Rahasyam

In the absence of Brahman there is no world; by the absence of that (world) there is no Hari. As Brahman alone is, be of the certitude that there is no non-self.-- Sri Siva Rahasyam
