mangna mangna hai....allah se mango ya insaan se...mangne me ek baat common hai ki jo mila hai us se person is not satisfied...he needs more or he needs that which has not been given to him by existence presently...god ki prayer mangna nahin hai it is thanksgiving to him that whatever you have given to me i m thankful for that...god you are more intelligent than me...you know what is right for me...if you are giving me pain certainly there will be some purpose in it....bhagwan se mangna use ye kehna hai ki tune jo diya hai wo kafi nahi....
