It is a hot summer day，and you feel thirsty．A friend gives you a glass of cold lemonade．How do you feel when you see the glass? Will you describe your feeling as happiness or as pleasure? I believe you will say it is a feeling of pleasure．There is a connection between these two kinds of feelings，and sometimes one causes the other，but they are not the same．Pleasure is a more dependent on the five senses while happiness is independent of them．   

When you are happy，little unpleasant events usuallv do not disturb you．When you are unhappy，you feel as if everything is against you．You may compensate for it by eating chocolate and sweets because this gives you pleasure，yet you stay unhappy．A person may smoke cigarettes because it gives him pleasure，yet this does not make him happier，especiallv if he knows the fact that it is not good for his heahh．   

The physical world is always in a changing state．At each moment a new thing is being created，changed，transformed and then destroyed．This is the normal state of things and no one  can change it．If we stay still in a certain state，we are sure to experience unhappiness sooner or later．0n the other hand, if

we adjust to the environment，nothing can influence our moods．Then outer events have nothing to do with our inner joy of mind．  

The room of the mind is filled with worry or fear．If you are free of thinking about them，the room has been emptied，and  then you will see what is happening and experience it．When your mind stays quiet，you will see that happiness comes from the inside．
