Dalai Lama and the Open Heart

Before meditating in the evening, I read from the Dalai Lama's book called the Open Heart.  If you are wondering what enlightenment means, this is a simple exposition of something that might take a little time or none at all.  If you accept and practise the premise that no thing lasts and that the All is the reality.  So, while on the way, he says that the heart can have no corners of distrust or hatred or jealousy  and that to have an open heart is our daily practice.  Whenever the mind suggests to the heart that there is something to be liked, to be hated, to be appreciated, to be shunned, to be loved, to be eaten or to be drunk, the heart makes itself into that shape; it has you on one side and the object on the other side and it is a divided heart.  The cheering thing to remember is that this isn't the natural state, this is the Open Heart and we have simply generation by generation forgotten our real nature so much so that the real One has to keep sending messengers; Buddha, Christ, Mohammed, Hermes, Socrates, all the prophets and angels have to keep acting in our world to flag up our remembering and forgetting.   How it would be to be enlightened and still be in the world, I think it would all seem quite different.
