It is true that not everyone is ready for Buddhism yet. But to say therefore that we should teach a religion that is false but easily understandable so everyone can practise it is ridiculous. Buddhism aims at the truth and if not everyone has the capacity to understand it yet, they perhaps will be ready for it in their next life. However, there are many who, with just the right words or encouragement, are able to increases their understanding. And it is for this reason that Buddhists gently and quietly strive to share the insights of Buddhism with others. The Buddha taught us out of compassion and we teach others out of compassion.
