One thing is for certain. Pleasure is not happiness. Pleasure comes from outside whereas happiness comes from inside. Pleasure is ephemeral and happiness is enduring. Just look at the trees, look at the birds, look at the clouds, look at the stars….and if you have eyes you will be able to see that the whole of existence is joyful. Everything is simply happy. Trees are happy for no reason; they are not going to become prime ministers or presidents and they are not going to become rich and they will never have any bank accounts! Look at flowers - for no reason. It's simply unbelievable how happy flowers are.
