प्रत्यग्बोधो य आभाति सोऽद्वयानन्दलक्षणः ।अद्वयानन्दरूपश्च प्रत्यग्बोधैकलक्षणः ॥ ३९ ॥
In plain words
The inner consciousness that shines forth is defined by non-dual bliss, and conversely, that whose form is non-dual bliss is defined solely by inner consciousness.
Close to the Sanskrit
That inner consciousness which shines forth is characterized by non-dual bliss, and whose form is non-dual bliss has inner consciousness alone as its characteristic.
