7. Mistakes, Dissapointments & Failures - I guess these are all a very important part of our lives. I feel these are our (general) ways of Learning & thus growing in knowledge (especially concerning life & its hurdles).
             And these also serve a very crusial purpose - these keep on reminding us that we are humans & not some superior being. So, these help us to be humble & also to treat others with minimal respect (which is due to every being).  

         8. Attahed-Detachment refers to a 'state' of being in . It means that we should be having Unconditional Love - when dealing with/in relations & Hope for every other thing/event.
             I would like to acknowledge here that this term was first explained to me by Mr. Mani V. Paul . I hope I've done justification to his explaination .

         9. The advantages of being Truthful are :
                  (1). You remain free of any feelings of Guilt.
                  (2). People will be able to know your true self & so will be able to Trust you without                         any hesitation .
                  (3). You don't have to waste your precious energy in trying to impress others, since you                          will be your own self.
                  (4). Others will reciprocate positively by being themselves truthful , to you.
                  (5). You'll be ensuring that people except you for what you are. And so you'll know that                         they won't have any misconceptions about you . They'll know what to & what not                         to hope from you . And they'll also be in a better position to understand your                         actions/manner in the concerned circumstances. So, it'll reduce explaining on your                         part.
