Explaining Dhamma

You asked why it was that you cannot explain Dhamma to other people.

That ability is probably a matter of innate tendencies (most likely based on kamma), and I doubt whether you can do much about it. We read that Acharn Mun was superb at giving talks and explanations of Dhamma, but Acharn Sao (his teacher) would speak only a couple of sentences and go silent; and this despite the fact that he was also an Arahant.

It is just possible that, as your citta develops more in Dhamma, you will be able to teach in a style of your own. Time alone will tell.
