KATHOPNISHAD CHAPTER 2- SHLOKA 17

                                                   एतदालम्बनँश्रेष्ठमेतदालम्बनं परम् । 

                                               एतदालम्बनं ज्ञात्वा ब्रह्मलोके महीयते ॥ १7

              ETAD ALAMBANAM SHRESHTAM ETAD ALAMBANAM PARAM|

               ETAD ALAMBANAM DNYATVA BRAHMALOKE MAHIYATE ||17

               THIS SUPPORT IS SUPERIOR THIS SUPPORT IS HIGHEST,ONE 

      WHO KNOWS ABOUT THIS (SUPPORT ) IS ADORED IN BRAHMALOKA ||17

    This is continuation of what we are told in past . The Yama, the God of Death is telling that the knowledge that one gets with -THIS ,is highest and greatest  and one who has it is adored even in BRAHMALOKA . In Hindu concept there are different LOKA or different plains . The earth is BHU Loka  and there are some which are bellow this level and there are some which are Higher than this earth level. So the highest Loka is SATRY LOKA OR BRAHMA LOKA . 

   We all want to be in that Loka or plain This is considered the highest achievement when one does meditation and then has achieved closest place to the BRAHMA or may be BRAHMAN. Once we reach this plain,, there is no cycle of birth and death. So Yama is telling Nachiketa that this is the highest achievement and once you have the knowledge , you will be there and will be respected there.

    I am not sure why he is talking about SUPPORT. I think it may have to do with the Human being concept of what is higher . If a ball is thrown in air , it will come down. So in our human mind we have 7 plains ABOVE THE EARTH LEVEL  and there are 6 BELLOW THE EARTH LEVEL . So with continuation of practice of meditation and getting the KNOWLEDGE, one goes to HIGHER planes  and if one does not BEHAVE then he /she will FALL down to lower plain. So one has a support in this plain and one does not fall from there.
