The Key to Happiness

If you want to live in a state of happiness, you must learn the
difference between need and desire.

f you can be satisfied with what you already have, you
Ican certainly achieve happiness. But if you can only be
satisfied with more and more material things, you can
never achieve happiness. Happiness is a state of mind.
Nothing of a material nature can bring you happiness.
If you have in your mind a list of all the material
things that you want and you believe that by acquiring
every single thing on that list, you will be happy, then
it will be impossible for you to attain happiness. The
fact is that this material list has an end on paper, but
not in your mind. If you do not learn to stop your mind
running on in this way, it will keep on adding on more
and more items. And, you will always remain insatiable.

If you want to live in a state of happiness, you must
learn the difference between need and desire. The
real needs of a human being are quite limited. There
is always a full stop in the list of real needs, but the
list based on desire has no full stop. Every day you will
include a comma, and this will continue endlessly till
the day you die. A human being, by nature, is insatiable.
