You can go a step higher than St. Paul. Deux Factus Sum: ‘I am become Divinity!’ The top of the mountain. You can’t get any higher than this.
The earliest declaration, without qualifiers or compromises which reads: ‘I am Divinity!’ is found in the Bṛhadāraṇyaka Upaniṣad:
Ahaṁ Brahmāsmi: ‘I am Brahman‘. Short, simple, take it or leave it.
In its proper interpretation, the opening word Ahaṁ in its breakdown by syllable has the same interpretation as the Mantric expression AUM [see the Post]. And Brahman is a complicated word not identical with ‘Divinity’ as commonly understood.
But for as far back as I recall it has been understood as: ‘I am Brahman‘.
Though unlike elsewhere, nobody got killed for saying it. In fact, quite the opposite. It became a cliched term, a pretense at philosophical depth from the incorrigibly callow.
In today’s India the phrase ‘I am Brahman‘ said with enough gravity and vigor will get you a supplicant crowd by lunchtime and by sunset you will be settled in the Guru-Business. And there is no business quite like it.
