In the heart of winter, the chill freezes lakes and rivers; water becomes so solid that it can bear men, beasts and carts. As the spring approaches, earth and water warm up and thaw. What then remains of the hardness of the ice? Water is soft and fluid, ice hard and sharp, so we cannot say that they are identical; but neither can we say that they are different, because ice is only solidified water, and water only melted ice.
The same applies to our perception of the world around us. To be attached to the reality of phenomena, to be tormented by by attraction and repulsion, by pleasure and pain, by gain and loss, fame and obscurity, praise and blames, creates a solidity in the mind. What we have to do, therefore, is to melt the ice of concepts into the living water of freedom within. All phenomena of samsara and nirvana arise like a rainbow, and like a rainbow they are devoid of any tangible existence. Once you have recognized the true nature of reality, which is empty and at the same time appears as the phenomenal world, your mind will cease to be under the power of delusion. If you know how to leave your thoughts free to dissolve by themselves as they arise, they will cross your mind as a bird crosses the sky - without leaving a trace.
Maintain that state of simplicity. If you encounter happiness, success, prosperity, or other favorable conditions, consider them as dreams and illusions, and do not get attached to them. If you are stricken by illness, calumny, deprivation or other physical and mental trials, do not let yourself get discouraged, but rekindle your compassion and generate the wish that through your suffering all beings' sufferings may be exhausted. Whatever circumstances arise, do not plunge into either elation or misery, but stay free and comfortable, in unshakable serenity."
