The transformation of the world is brought about by the transformation of oneself. - Jiddu Krishnamurti

Most people have lost that relationship with Nature; they look at all those mountains, valleys, the streams and the thousand trees as they pass by in their cars or walk up the hills chattering, but they are too absorbed in their own problems to look and be quiet.

To find out if there is actually such freedom one must be aware of one's own conditioning, of the problems, of the monotonous shallowness, emptiness, insufficiency of one's daily life, and above all one must be aware of fear. One must be aware of oneself neither introspectively nor analytically, but actually be aware of oneself as one is and see if it is at all possible to be entirely free of all those issues that seem to clog the mind.
To explore, there must be freedom, not at the end, but right at the beginning. Unless one is free one cannot explore, investigate or examine.
Two things are essential: freedom and the act of learning. One cannot learn about oneself unless one is free, free so that one can observe, not according to any pattern, formula or concept, but actually observe oneself as one is.

So you must ask this question, put this question to yourself, whether your mind can be empty of all its past and yet retain the technological knowledge, your engineering knowledge, your linguistic knowledge, the memory of all that, and yet function from a mind that is completely empty. The emptying of that mind comes about naturally, sweetly without bidding, when you understand yourself, when you understand what you are. What you are is the memory, bundle of memories, experiences, thoughts. When you understand that, look at it, observe it; and when you observe it, see in that observation that there is no duality between the observer and the observed; then when you see that, you will see that your mind can be completely empty, attentive, and in that attention you can act wholly, without any fragmentation.
