KATHOPNISHAD CHAPTER 3 SHLOKA -8

                                                       यस्तुविज्ञानवान्भवति 

                                                     समनस्कः सदा शुचिः । 

                                                       स तुतत्पदमाप्नोति  

                                                    यस्माद्भूयो न जायते॥ ८

                                   YASTU VIDNYANVAN BHAVATI

                                    SAMANASKAH SADA SHUNI |

                                     SA TU TAT PADAM APNOTI 

                                    YASMAT BHUYO NA JAYATE ||8

ONE WHO IS KNOWLEDGEABLE,ONE WHO HAS MIND CONTROL,

WILL REACHES THE THAT GOAL FROM WHERE (HE) IS NEVER BORN AGAIN ||8

    This SHLOKA is again the same thing that we were told in last one but in a positive way . In Shloka 7 we were told that one is who is ignorant and one who has no control of mind, will be born again . In this one we are told as to who will be NOT born again. Remember Nachiket asked the question as to what happens after the death of physical body and Yama is telling him as to how to avoid the rebirth or the cycle of birth and death. So we are told that when one is gotten the knowledge and one who has control of the mind , will not be reborn This is simple to understand  and there is nothing new in this statement . The question is why do we get rebirth ? The answer will lead to the answer that is given here. When we do things with attachment we are bound  and then that binding  leads to desire  and that desire has to be satisfied  and since we do not have physical body after the death, we have to be reborn as to get physical body ,so that we can satisfy out desires  and fulfill attachments. 

    So the only way to be not borne again is to have no DESIRES  and as mentioned by many one can not live without the action, one must do action without attachment. If we do Karma with no desire or expectation, we will not have attachment and so we will be free of the desires  and that will end the cycle of birth and death. 

   So this the knowledge  and one who acts on it -control of mind -will not be reborn.

KATHOPNISHAD CHAPTER 3 SHLOKA 7

                                                           यस्त्वविज्ञानवान्भव

                                                       त्यमनस्कः सदाऽशुचिः । 

                                                         न स तत्पदमाप्नोति

                                                        संसारं चाधिगच्छति ॥ ७

                                             TASTU AVIDNYANVAN BHAVATI

                                             AMANASKAHA SADA ASUCHIHI |

                                               NA SA TAT PADAM APNOTI 

                                          SAUSARAM CHA ADHIGACHHATI ||7

      ONE WHO DOES NOT HAVE PROPER KNOWLEDGE,THOUGHTS,AND PURITY,

         NEVER ATTAINS THAT LEVEL-GOAL, AND GETS IN TO THE SAUSARA

                                   ( OF BIRTH AND DEATH CYCLE)||7

 In scriptures we have continuation of the same message in different forms or examples. Here in this Shloka we are told by Yamaraj that there are people who may seem to talk certain things that may be impressive and we may think that they have conquered the Death and Birth cycle. But in reality unless one has done certain things he or she will not get freedom from this Suansara where every thing is mortal. He is telling us the characters of some one who will achieve the goal  and will be free of death and birth cycle. So when one does not have the knowledge -and by proper knowledge he is not talking about physics or chemistry or biology but about something beyond the external appearance or things that can be perceived by sense organs . The entire science is devoted to findings more and more about things that can be perceived by our senses. We have made great progress in that direction. We did not know about atoms and then subatomic particles with microscopes or farther galaxies that are seen with telescope - but all of this is still dependent upon senses . We can do chat on phone or do video call and again that is sense dependent. But here we are not talking about that Knowledge. The real KNOWLEDGE is beyond the senses. Some people classify this as Gross-STHULA, Subtle -SUKSHMA , , SHUNYA and then SHIV , as 4 different levels . Shunya does not mean NOTHING but it is Nothing that can be perceived by senses. So when one has that knowledge then he is DNYANI. Proper thoughts  and purity of mind and action is also needed. Many may have it in OUTSIDE life  and behavior but not INSIDE. Such person may have read scriptures and understood them  and may have practiced them , but unless he has all the things that are mentioned above , he will not have freedom from mortal world. 

KATHOPNISHAD CHAPTER 3 SHLOKA 6

                                                                  यस्त्वविज्ञानवान्भवत्य

                                                                  युक्तेन मनसा सदा । 

                                                                  तस्येन्द्रियाण्यवश्यानि 

                                                                   दुष्टाश्वा इव सारथेः ॥ ५

                                                 YASTU VIDNYANVAN BHAVATI

                                                     YUKTEN MANASA SADA |

                                                   TASHYA INDRIYANI VASHYNI 

                                                      SADASHVA IVA SARTHEH||6

                    THE PERSON WHO HAS ALWAYS  CONTROLLED HIS MIND 

                                      WITH RIGHT UNDERSTANDING 

                      HIS SENSES ACT LIKE GOOD HORSES OF A CHARIOTEER ||6

     This Shloka is continuation of the last one . In last one we were told about the uncontrolled senses and their problem like uncontrolled horses of a chariot. But if the charioteer is skilled  and keeps the horses are kept under control, then the chariot will move smoothly and reach the destination. One difference between the chariot  and horses and the mind  and the body is that we are talking about the understanding or the knowledge. The horses are trained  and the charioteer has not only the reins but also has stack ,in case the horses don't behave . In human beings just controlling the  senses and subsequently the action is not enough. So we may act as civilized person and not grab food at a party till it is served, but if we continue to have the desire  and the mind is not under our control where it does not even has desire or lust, then only we will be successful in reaching the destination. So it is good to have GOOD behavior  and not act irrational, but as long as we have not conquered the mind and the desires or lust , we will not get to our goal. 

    So the Shloka used the word VIDNYAN- which means having knowledge -understanding. So it is not just passive control of action but cutting of the origin of action -desire- with knowledge.
