Mandukya Upanishad
“The supreme reality into which we merge in the “Fourth” state (Turiya)
Is also represented by the Sacred Syllable : AUM : ॐ
AUM stands for mantram - a form of sacred utterance
To still the mind
And become aware of the divine reality to which it refers
All mantrams according to Mandukya Upanishad
Go back to AUM ॐ and then beyond
Even that primordial energy to Brahman- The ultimate goal of Spiritual progress
