                                                         नेह नानाऽस्ति किंचन ।

                                                          मृत्योः स मृत्युं गच्छति

                                                         य इह नानेव पश्यति ॥ 11

BY MIND ALONE THIS CAN BE OBTAINED,THEN THERE IS NO DIFFERENCE HERE OR

               THERE ,HE WHO SEES DIFFERENCE GOES FROM DEATH TO DEATH ||11

In the last Shlok we were told that there is no difference between Here and or There. Now in this Shlok, we are told that this -BRAHMAN can be achieved only by mind . So There is no difference between the BRAHMNAN -which we think is THREE  and this visible Universe. This is the forest step in understanding of the BRAHMAN. The visible and non- visible Universe is one and the same . or that the visible universe is nothing but Brahman in different form, Let us take an example of a wooden desk . The Desk is of different shape or form than the tree from where the wood came from . But the desk is wood though out (barring nails and glu and may be mica).But we recognize desk as DESK and not wood, But upon further inspection , we KNOW that the desk is nothing but wood in different form. But the wood and the the desk are different from my body . But If we all are created by the GOD- BRAHMAN or we all came from Brahman, and there is nothing 'outside' the Brahman, then we must be BRAHMAN in different form Other example can be spider and spider web . The Web comes out of spider . So something like that we came out of Brahman and so there is no difference between everything in this universe  and the originator Brahman . We have to understand this  and we have to understand it with our MIND. 

        This is little different than what we were told or understood - BRAHMAN is BEYOND mind ,intellect or ego.-things that are related to PRAKRUTI or NATURE. So we have or we are BRAHMAN  and we have to understand it with mind  and then when we find no difference between different things in this universe and beyond, the cycle of death and birth ends .If we continue to think that  things in this universe are different from each other and Brahman, then we can not be one with Brahman.
