When you think of it, really there are four fundamental questions of life. You've asked them, I've asked them, every thinking person asks them. They boil down to this; origin, meaning, morality and destiny. 'How did I come into being? What brings life meaning? How do I know right from wrong? Where am I headed after I die?'
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.
