Unremitting Sadhana Required

The Ribhu Gita (ऋभुगीता) forms the sixth part of Siva Rahasya Purana. It details in about two thousand verses the dialogue on the Self and Brahman between Sage Ribhu (who in turn heard it from Lord Shiva Himself) and Sage Nidagha on the slopes of the Mount Kedara in the Himalayas. (source: wikipedia).

• The illusion that one is the body and that the world is the basic reality has remained over a long long time, and cannot be got rid of by the casual reading and mere understanding of the truth. The basic illusion can be effaced only by a long and unremitting practice of the bhavana that all this is 'I am Brahman Self'.
• Everything is only a conception 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, 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.
• There is never such a thing as conception of names and forms, no such thing as the conceiving mind, no such thing as a person lost in samsara, and no such things as the world and its creator. Everything that is seen to exist must be realized to be no other than the sole, pure Awareness-Being-Brahman-Self.
