Ekanta
om sai ram
If it is 'achintyam', 'avyahāryam, 'alakshanam', then it would also be totally 'avijneyah'. It is like saying God is 'unknowable' but 'I know God'. Many scriptures fall at this. I like the Brahma Sutra approach better, step by step - 'atha Brahmajijnasa'. Let us discuss what we can find out.
Some food for thought:
Mandukya Upanishad Karika 3.33:
They say that the non-conceptual knowledge, which is birthless, is non-different form the knowable (Brahman). The knowledge that has Brahman for its content is birthless and everlasting. The birthless (Self) is known by the birthless (knowledge).
Relevant Upanishads:
for the knowers function of knowing can never be lost (BrU 4.3.30)
Knowledge, bliss, Brahman (BrU 3.9.28:7)
Brahman is truth, knowledge, infinite (TaiU 2.1.1)
Shankaras comment: that very knowledge of Brahman is non-different from Brahman, as heat is form fire The idea is that the Self being ever a homogeneous mass of Consciousness, like the sun that is by nature a constant light, does not depend on any other knowledge (for Its revelation).
