Summary of Sloka 256:

That which is supreme, beyond the reach of all speech; that which is seen by that eye of wisdom, which is free of defects;  that chit which does not refer to sense objects, that being which is without a begining; Meditate on that, that thou art,  in your mind;

That which is supreme, beyond the reach of all speech; that which is seen only by that eye of wisdom, which is free of defects; These are all desciptions, we head from Vedas. "यतो वाचा निवर्तन्ते" is an oft heard statement of Vedas. Brahman is beyond speech and cannot be comprehended by naked eye. That chit which does not refer to sense objects, is that mind which does not run after sense objects. Only such a mind can comprehend the  true nature of Brahman. That is the summary of the Sloka .

Here, Guru having told the disciple that  तत् त्वम् असि, that you are that Brahman, now elaborates on that 'तत्' ; In the next few Slokas Guru elaborates on that Brahman. 

Sloka 257:

षड्भिरूर्मिभिः अयोगि योगिहृत्
भावितं न करणैः विभावितम्।
बुद्ध्यवेद्यमनवद्यभूति यद्
ब्रह्म तत्त्वमसि भावयात्मनि॥

षड्भिः ऊर्मिभिः अयोगि  -
that which is not affected by the six waves

योगिहृत् भावितं -
that which is meditated on in the minds of Yogis
 
न करणैः विभावितम् -
that which cannot be apprehended by the senses-organs;

बुद्ध्या अवेद्यम् -
that which is unknowable by the intellect

अनवद्यभूति यद् ब्रह्मम् -
that which is of flawless excellences

तत्त्वमसि भावयात्मनि -
'thou are that' , meditate on that in your mind;

Summary:

"That which is not affected by the six waves ; that which is meditated on in the minds of Yogis ; that which cannot be apprehended by the senses-organs; that which is unknowable by the intellect ; that which is of flawless excellences ; 'thou are that' , meditate on that in your mind";

The six waves, referred to by the Guru, are the hunger, thirst, grief, delusion, old age and death; The self is un affceted by these six. That Brahman/Self is meditated on by the Yogis . That Brahman - Self is beyond sense organs which means that that it cannot be comprehended by speech, beyond recognition by eye, beyond touch, beyond being able to be grasped by anything. But it is grasped by the eye of wisdom.

When guru said  - बुद्ध्या अवेद्यम् - unknowable by the intellect. he is referring to the intellect devoid of discrimination. Only an intellect sharpened by the ability of discrimination can recognize the Brahman. .
