    This shloka tells us something that we have heard before  and we know about it but have not experienced it . We have heard all sorts of things about Knowing the SELF  and how do you feel when you achieve the goal. So Lord of Death is using the language that we all know very well. If I ask someone who loves sweet deserts as to how you feel when you eat it, He will answer that it is most joy that I can imagine or it is like as if you are in heavens. So we all know the Joy and happiness. We all do EVERYTHING in life to be happy or get Joy . One can look at our behaviors, we are always trying to be Happy and seek comfort . We sit not on a hard surface as we want to be comfortable. We have temperature control with Air Conditioning or heat so we have comfortable temperature  and we cook only that food that we like  and every other thing that we do is for comfort. But as mentioned in past these all things that cause happiness are not permanent . Her we are told that when once we have understood the ATMAN or the SELF  and experienced it, we have most joyous experience  and the SELF is the source of all joy. 

     We are also told that not only the experiencing the SELF is joyous , but IT is the source of Joy. One can think of this as 2 different way. One is that without the ATMAN or SELF ,which is different that physical body mind intellect - all part of PRAKRUTI, we can not experience the JOY . The second way is that the SELF has created everything that gives us the JOY (and also the things that give us sorrow)But please remember that the SELF is independent witness  and the JIVA which is limited to Body feel that it is part of the body and is ENJOYING all the pleasures. 

   He is also telling that once you have this you have wide open the house of Brahaman This is like getting in to exclusive club where you have to fulfill all the requirements for the admission to the club and once you pass all the tests, you can enjoy all the things that the club offers - golf ,tennis , dinning room and many other . So here we are told that Nachiket, now the entire home of BRAMAN is open to you .
