Nidaga Enlightened

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 following verses contain the declarations of the disciple Nidaga before his teacher Ribhu, expressing the spiritual achievements secured by him by the grace of his teacher, and expressions of his gratitude to his teacher, Ribhu.

• O Lord Sat Guru! By thy grace I have, in a split second, shed all sense of differentiation of Self and non-Self. I have attained the certainty that all is Brahman and I am that Brahman Self, I have become settled in the eternal bliss of Brahman Self.
• I am verily the SatChitAnanda Brahman Self. I am the eternal undisturbed peace devoid of name and form. I am the flawless integral whole of all existence. Firmly I am settled in my sole Brahman Self. 
• I have become Brahma, Vishnu, Rudra, Mahesha, sadashiva, Parameshwara and his spouse Parvati, Vinayaka, Subrahmanya, cohorts of sides hosts (Shiva ganas) and devotees of Lord Shiva, all rolled into one!
• I am myself the devas and asuras, Indra, the Lord of the eight cardinal directions, the community of sages, the swarm of rakshasas and the denizens of this and all other worlds.
• I have become the five elements, multitudinous worlds scattered in the skies, all existing things and their histories and all the Vedas and all the diversities of name and form.
