Yes, K?l?mas, it is proper that your have doubt, that you have perplexity, for a doubt has arisen in a matter which is doubtful. Now, look you K?l?mas, do not be led by reports, or traditions, or hearsay. Be not led by the authority of religious texts, not by the delight in speculative opinions, nor by seeming possibilities, not by the idea: 'this is our teacher'. But, O K?l?mas, when you know for yourself that certain things are unwholesome, and wrong, and bad, then give them up... And when you know for yourself that certain things are wholesome and good, then accept them and follow them.
Once again, we are reminded that awakening, or enlightenment is not the property of Buddhism, any more than Truth is the property of Christianity. Neither the Buddha nor the Christ belongs exclusively to the communities that were founded in their names. They belong to all people of goodwill, all who are attentive to the secret which lives in the depths of their breath and their consciousness. (14)
People sometimes imagine that without desire there would be no enjoyment. The opposite is true. When you're caught up in craving, you never really enjoy anything very much because your mind is always pulling you on to the next desire and the next after that. When you let go of desire, then you're free to enjoy whatever is right in front of you.
First of all, Buddhism is neither pessimistic nor optimistic. If anything at all, it is realistic, for it takes a realistic view of life and the world. It looks at things objectively (). It does not falsely lull you into living in a fool's paradise, nor does it frighten and agonize you with all kinds of imaginary fears and sins. It tells you exactly and objectively what you are and what the world around you is, and shows you the way to perfect freedom, peace, tranquility and happiness.
