The highest-expression of Intellectual Hinduism [in counterpoint to the popular paths of Ritual Observance or Devotional Service] was set-forth by Shankaracharya:
Para Brahman was as Nirguṇa Brahman. The highest expression of the Truth of Brahman was as ‘Brahman without attributes’.
If something doesn’t have attributes you cannot express it except as: ‘That without Attributes’
Is that a Self-Eating Expression?
Vedantha’s roots are in the Ajātivāda of Gaudapada itself drawn from the Prajna-Paramitha texts. Brahman was originally a Mantric expression for Yagnic formalities before it took on metaphysical meanings. See the later Posts on Advaitha Vedantha.
