And after reading Thoreau I felt how much I have lost by leaving nature out of my life.

"If you lose touch with nature you lose touch with humanity.
If there's no relationship with nature then you become a killer;
then you kill baby seals, whales, dolphins, and man
either for gain, for "sport," for food, or for knowledge.
Then nature is frightened of you, withdrawing its beauty.
You may take long walks in the woods or camp in lovely places
but you are a killer and so lose their friendship.
You probably are not related to anything to your wife or your husband."

It's very, very dangerous to lose contact with living nature.

Now, to look is one of the most difficult things in life – or to listen – to look and listen are the same. If your eyes are blinded with your worries, you cannot see the beauty of the sunset. Most of us have lost touch with nature. Civilisation is tending more and more towards large cities; we are becoming more and more an urban people, living in crowded apartments and having very little space even to look at the sky of an evening and morning, and therefore we are losing touch with a great deal of beauty. I don’t know if you have noticed how few of us look at a sunrise or a sunset or the moonlight or the reflection of light on water. Having lost touch with nature we naturally tend to develop intellectual capacities. We read a great many books, go to a great many museums and concerts, watch television and have many other entertainments. We quote endlessly from other people’s ideas and think and talk a great deal about art. Why is it that we depend so much upon art? Is it a form of escape, of stimulation? If you are directly in contact with nature; if you watch the movement of a bird on the wing, see the beauty of every movement of the sky, watch the shadows on the hills or the beauty on the face of another, do you think you will want to go to any museum to look at any picture? Perhaps it is because you do not know how to look at all the things about you that you resort to some form of drug to stimulate you to see better.

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.

But if you have no relationship with the living things on this earth, you may lose whatever relationship you have with humanity.

A real relationship with nature is vital for our magical and spiritual development, and our psychic and spiritual health. It is also a vital base for any work we do to heal the earth and transform the social and political systems that are assaulting her daily.

The recognition of oneself as a part of nature, and reliance on natural things, are disappearing for hundreds of millions of people who do not know that anything is being lost.

The deeper the soul plunges into religious religious devotion, the more it loses all sense of reality, all need, all desire, all love for reality.

He had missed the deepest of all companionships, a relation with the earth itself, with a countryside and a people. That relationship he knew cannot be gone after and found; it must be long and deliberate, unconscious. It must, indeed, be a way of living.

It is odd that we have so little relationship with nature, with the insects and the leaping frog and the owl that hoots among the hills calling for its mate. We never seem to have a feeling for all living things on the earth. If we could establish a deep abiding relationship with nature we would never kill an animal for our appetite, we would never harm, vivisect, a monkey, a dog, a guinea pig for our benefit. We would find other ways to heal our wounds, heal our bodies. But the healing of the mind is something totally different. That healing gradually takes place if you are with nature, with that orange on the tree, and the blade of grass that pushes through the cement, and the hills covered, hidden, by the clouds.

Only when there is a wilderness can man harmonize his inner being with the wavelengths of the earth. When the earth, its products, its creatures, become his concern, man is caught up in a cause greater than his own life and more meaningful. Only when man loses himself in an endeavor of that magnitude does he walk and live with humanity and reverence.

At difficult times in my life Nature has always offered me refuge. For me it is not 'environment' or a 'place of leisure and relaxation' but a temple in which I experience feelings that are almost religious.

Somos culpables de haber destruido muchos dones de la naturaleza y de haber perdido toda espiritualidad.
