A Prayer to Who is One Eternal Pure and Changeless

I prostrate myself before that Sat Guru, the Brahman
Who is Bliss;
Who is giver of Supreme Happiness;
Who is the Absolute;
Who is the form of Knowledge;
Who is beyond the Pairs of Opposites;
Who is vast like Ether;
Who is attainable through assertions like “Tat Tvam Asi,”
Who is One, Eternal, Pure and Changeless;
Who is the witness of all the states of the Mind,
Who transcends Modifications;
Who is devoid of the three modes of Prakriti
