[tet68]

Behold the void!
Consider it not the void of nothingness
but thine own intellect, blissful and shining.

[Candor7]

but thine own intellect, blissful and shining.>>>>>>>>>>>>

Thine own intellect is merely a construct which must be maintained continually. At death it ceases to exist. It is called the ego, which is non existant. As such we work to continually maintain who we are, a continually evolving self image.

So thine own intellect shines only for ones self.make it transparent through Shamatha meditation, so one can not be tricked into thinking it is “Thine own intellect shining.”It has no independent existence except what we give it moment to moment.

What shines is not intellect, but ones own basic human nature, unconditional basic goodness or bodhicitta.To touch that one must rest ones mind in peace, slow the incessant discursiveness of thought and then see what lies underneath.The way is to practice Shamatha meditation .
