All Nothing But The Self

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 great illusions: maya (associated with God Ishwara), avidya (associated with individual souls), mind and jivas (souls), world and its creator, all names and forms, and all mental conceptions are nothing but the Self. One should ever abide in this conviction.
• All worlds and creatures are only thought forms. They are nothing but the mind, which is a bundle of thoughts, which again are nothing more than ripples in the still ocean of Awareness-Self, and certainly nothing apart from the Self. Therefore, one should abide in the firm conviction that all objects are only I Am Self-Brahman.
• There are no such things as achieved objectives and the efforts leading to them, association with the wise or the ignorant, efforts of learning and knowledge acquired, acts of enquiry and practice, the learner or the learned, and any goals achieved. What exists is only Brahman the effulgent Awareness-Self.
• One should be firm in the conviction that there are no charitable acts, sacred waters and kshetras, no loss or gain and no loser or gainer, no karma, bhakti and wisdom, and no knower or known. All these thought-forms are bound to be dissolved and lost in the Brahman-Self, which is the sole existence.
• The bhavana "I am Brahman Self" swiftly takes one to mukti. As the continued reading of the texts generating that bhavana, takes the aspirant unerringly to the goal, he should always dwell on the written words dealing with the Brahman Self.
