Keys to Natural Truth by Buddhadasa Bhikkhu

Keys to Natural Truth is the Book about Kalama Sutta , it help Us to know Two kinds of Language, Looking Within, Happiness & Hunger, The Dhamma - Truth of Samatha - Vipassana for the Nuclear Age.

The first, "Kalama Sutta, Help Us!" sets out a fundamental attitude of Buddhism.  We should believe something only after examining it, thinking it through carefully, trying it out, and finding for ourselves that it is correct. The Buddhist path of wisdom is meaningless for those who ignore this principle; they turn it into something else.

“Two Kinds of Language," the second key has still been long out of print.

"Looking Within," The third key shows us where to verify the truths taught by others. Here the Venerable Ajahn counteracts our tendency to be engrossed by external things and orients us in the direction of spiritual truth. He emphasizes that we must look beyond relative and superficial truth to find real truth. The key to doing this is "looking within." To help us begin this necessary introspection, he shows us the difference between observing external material phenomena and observing internal mental phenomena. Through the latter, the Dhamma may be realized directly and independently.

"Happiness & Hunger," the fourth key, the aim of this truth is to clarify the proper motivation for Dhamma study and practice. We tend to ask of Dhamma what it is not meant to provide. Sometimes we even play at Dhamma. Those who seek happiness would do best to find out what they really want, and whether or not the Dhamma can provide it.

The last key here, "The Dhamma-Truth of Samatha-Vipassana for the Nuclear Age," discusses a few important issues which are regularly confused. First, the way of life taught by the Buddha is one unified path. If we unnaturally cut it into pieces, it cannot function spiritually. If we try to practice just this aspect or that, we will never realize even that fragment, let alone the whole Dhamma. Second, we create our own problems and suffering; therefore we must solve them ourselves. We should not let our personal truths get in the way of the real truth which frees us. Lastly, we live in an increasingly dangerous world; we have no time to waste. We must be vigilant and practice earnestly.

Many people have contributed to this book, beginning with Ajahn Buddhadasa and the translators. With the help of Dhamma friends who have read and commented upon the articles, I have done some editing, primarily to harmonize style and terminology, as well as to bring out Ajahn Buddhadasa's message as clearly as possible. After that, Rod Bucknell has corrected my corrections. Then, the Dhamma Study & Practice Group has seen to the business and technical arrangements. And now you have this book in your hands, which fulfills the wish behind everyone's Dhamma-dana (gift of Dhamma).
